From the lb-ft Ram back in to the plus-lb-ft numbers of the current Big Three, diesel transmissions have one of the toughest jobs in the pickup truck industry.
This means that once power gets up to the hp level, nearly 1, lb-ft of torque is unleashed on the transmission. Pick the Right Starting Point Some transmissions are stronger than others right off the bat. Because the TF had proven itself behind the power of muscle cars for years, it was up to the task of the power and torque. At around to hp, these transmissions start having trouble and need parts like billet flexplates, input shafts, and torque converters. Unfortunately, they do have their weaknesses.
Boosted launches or locked shifts can break input shafts, rip out the center of flexplates, or even break output shafts. While a triple-disc converter and valvebody can be installed for a few grand, most performance enthusiasts opt for a full rebuild with a billet input and flexplate, just to be safe.
The newest transmission in the Ram line is the 68RFE, which in stock form is limited pretty closely to stock horsepower. This kit re-works the valvebody and TCM to where the 68RFE can live at to hp, but any more than that and the truck owner will have to start delving deep into the transmission. On the transmission front, most 4L80Es will be safe in stock form, because most hopped-up 6. If more transmission strength is desired, there is a robust aftermarket available to build these transmissions to handle 1, hp and 1, lb-ft.
These trucks were partnered with the Allison transmission, which is known for its strength. Unfortunately for the aftermarket, the Allison is also very smart, and it does things like de-fuel during shifts, drop mainline pressure when the converter locks, and go into limp mode if just a few-percent slip is detected. The Allison is hard to push past that in stock-ish form, because the clutches will slip, and the transmission will go into limp-mode to save itself.
In the case of both the E4OD and 4R, the converter clutch is the weak link and will start to slip before anything else gives. In the E4OD, this might happen as soon as rwhp, while the 4Rs will usually hold out until about rwhp.
Swap in an Overdrive
In completely stock form, we have seen these transmissions hold rwhp for years and up to rwhp for short bursts dyno runs, eighth-mile passes, etc. Eventually, the direct and overdrive clutches will show some wear, but usually not until at least a year or two of hard driving.
In all these applications, the clutch will be the initial weak link, but if that is replaced, then most of these transmissions are very strong—capable of handling to hp in daily driver situations. More Photos View Slideshow.Brother laser printer problems

While the Ford and Chevy guys might get a kick out of that, it should be noted that the car's demise was caused by a cracked aftermarket torque converter—the only non-Mopar part of its drivetrain. While the obvious fix would be to simply replace the lame torque converter with a Mopar unit, miles of high-rpm Power Tour driving before the breakdown suggested there might be a better alternative.
Why not install one of Chrysler's new four-speed overdrive automatics in place of the original Torqueflite? The reduced engine noise and improved fuel economy would make it even better for Power Tour ' First introduced for the Dakota trucks inthe A and A automatic overdrive transmissions are based on Chrysler's and Torqueflites, respectively.
Either transmission can be found in the Mopar Performance catalog, part No. P for the A and P for the Aand the gear ratios are identical to the older trannies, with the exception of the overdrive.Super junior super show 7 seoul dvd download
However, the catalog listing included the ominous warning, "requires major modifications on A-B-C-E body. As mentioned before, either tranny is available, but because it would be dealing with a plus-hpwe went with the beefier A and sent it directly to JVX, Inc.
The first thing we noticed when the new unit arrived at Art Carr was how closely it resembled an old The tranny's front half is identical to the old Torqueflite, and the A is only a few inches longer, with a thicker tailshaft housing for the overdrive mechanism. How tough could this install really be? Well, we can't say we weren't warned. As the Mopar catalog stated, a fairly "major" chunk of the driveshaft tunnel had to be "modified" before the tailshaft housing would clear the body.
About 1. Rather than creating a new piece from scratch, Art Carr's technicians used the original crossmember end pieces and fabricated a center section designed to match up with the A's lower rear mount.
Finally, the A's increased length required cutting the driveshaft down from On the plus side, the original starter, tranny cooler lines and throttle linkage worked with the new transmission. So while not exactly a "bolt-in" upgrade, getting the A to physically fit into an old B-body or E-body Mopar can be done, and much of the original hardware will bolt directly to the new unit.
But getting it to fit was only half the battle. Now we had to figure out how to make the GTX shift into a gear it was never meant to have. As with the physical installation, it was almost as if Chrysler planned on people doing this conversion.
First, the A continues to use only six shifter-selector positions rather than having the "OD" position that GM and Ford use. This means that with a column-shift musclecar, the shift linkage will completely bolt up. The GTX's floor shift, however, required some additional custom fabrication to get the shifter to operate the A Once bolted up, the linkage banged into an unused ear on the tranny's case, so it was ground off, giving the linkage plenty of clearance to operate smoothly from Park to First gear.Installation — All linkage, vacuum lines and kickdown mechanisms must be connected and properly adjusted for any automatic transmission to operate correctly.
We recommend the use of a Hughes Performance trans. We also recommend the use of a cooler with the use of any high-stall torque converter application. This particular transmission fits many GM rear wheel drive O.

It's what I do for fun. Joel, excellent post. Thanks for it. I've got my 3rd!! Should I adjust the bands? I don't know squat about these things either but I am a quick study. Thanks again! Eric ericschmidtenator gmail. Thanks Eric. For your issue I would guess there's a problem with the throttle position sensor which is mounted on top of the injection pump on the engine.
It's basically a potentiometer that tells the computer how much fuel your giving the engine. It helps the computer determine when to engage the OD since it's an electrical shift. You mount the potentiometer on your dash, and you can dial in a shift point for the OD.
I've done this to mine, and I have it set to shift the OD at 35mph. When I'm towing my fifth wheel I dial it up to shift around 45mph. Let me know if you want more info on this. I did a write-up on it on dieseltruckresource. It's a nice forum with lots of friendly people and lots of valuable information.
You can always adjust the bands, but it won't help this problem : I. Post a Comment.In order to understand what a core charge is, you must first understand what a core is. In the automotive industry, most products are manufactured from brand new materials. However, numerous products are also remanufactured, meaning that the manufacturer of the product takes a used product, typically removed from a vehicle, disassembles, and replaces all worn components of the master product.
A great example of this is in regards to automatic transmissions in which the manufacturer takes an existing transmission, replaces all of the inner working components, such as the torque converter, valve body, etc. Because aftermarket manufacturers require a steady stream of incoming cores to build, they charge a deposit on the core, known as a core charge, that is refunded upon receipt.
In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable. If you plan on returning your core you have two options. You still have the option to send it back, and if you do, the core will be refunded back on the card used, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order.
If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us. If you defer it, you will not be charged a core at time of purchase.
You will have 21 business days from the day you receive it to send it back. As long as the core is received within the 21 business days, you will not be charged. If 21 business days goes by and you do not send it back, the card on file will be charged the core amount. You still may send it back, and once received, we will issue the core amount as in store credit, pending any limitations as set forth by the manufacturer.
Core deferral is limited to payment by credit card only.
Your transmission was only designed to handle the torque and horsepower the stock engine delivers, and in the case of some Dodge models, even No Salesmen, Just Enthusiasts Reviews may be edited for spelling or grammar inaccuracies and those containing profanity will be removed. At this time no, we must receive the same unit back. Unfortunately non of the overdrive transmissions will work on your truck without modification. Since your truck has nothing that would make it go into overdrive.

All cores, whether the core charge was deferred or not, must be returned within 21 days from delivery date of product requiring core charge.
Failure to do so can result in forfeiture of the entire core charge return. In the event you originally deferred the core charge, you authorize Diesel Power Products to charge you for the core charge.
All cores must be returned to the original warehouse that original shipment was sent from. If a return label is provided in the original shipment, use this tag.Dodge Conversion. This is how to replace your three speed transmission with a back A overdrive transmission with a three wire connector gas.
Remember overdrive is only 3rd gear high range anyway. There are two wire transmissions out there, these have a non-lock-up torque converter. With this three wire setup you have a four speed transmission plus a torque converter lock-up feature. The extra gear is 3rd high range. This will be accomplished with the use of three GM parts and some trick wiring.
This can be made to work with a diesel motor also with or without a vacuum pump and vacuum regulator. We sell the parts for this transmission swap.

The front wire is the overdrive ground and the rear wire is the torque converter lock-up ground. You can get a three wire female connector from a junk yard or buy one from us. Run a 12 volt fused wire that turns on and off with the key to the vacuum switch, then to the center wire on the transmission connector. This is a normally open vacuum switch that takes 7 inches or more of vacuum to shift into overdrive and lock-up the torque converter and 3 inches or less of vacuum to down shift and unlock the torque converter.
At the governor pressure tap on the transmission install a tee fitting for two oil pressure switches. Or any other combination of switches you may want. At light throttle the transmission will shift into overdrive at 44 MPH and the torque converter will lock-up at 52 MPH.

The pressure switches go on the outside of the transmission case in the governor pressure port. The figures on the pressure switch will only be correct if you have a stock tire size and rear end ratio.Automotive OEM and aftermarket customers deserve original thinking.
