One workaround is to monitor PID data on a scanner. Ford specifies a special tool for the adjustment, but some shops aren’t going to have access to one. In most cases this can be corrected with a simple adjustment of the sensor. The most common symptom is delayed or no reverse engagement. On the Chrysler RWD vehicles, make sure that there is a return spring on the throttle lever (at the transmission), or you will end up with harsh downshifts.įord Explorers equipped with the 5R55W/S transmission seems to have the most claims that are generated due to MLPS problems.

Most other types of units utilizing a throttle cable are much simpler to set up, as they only require synchronized TV movement with the engine throttle. This is a critical setting for these units and use of a pressure gauge is the only sure way to get it right. If you call in a claim on one of these units, the first words you will hear from us are, “What is the pressure reading at factory idle speed?” If you don’t have the answer, we will request a call back with that information. There is only one way to properly set up these units to shift correctly (and make them survive): a pressure gauge. Though these units haven’t been in OE production for over a decade, they are still very popular: Some manufacturers require more complicated procedures, so research may be required for specific vehicles.
The upshift relearn is normally performed with 5-10 shift cycles through all gears at 20-25% throttle angle. In some cases, this is all that’s required. There is a procedure known as “garage shifts” that involves engaging the unit into reverse five times with a 5-second interval, and the same into forward.

Some must also learn how to engage into forward and reverse without excessive bump. After the procedure was performed with OE equipment, the unit worked perfectly.Īfter the shift-adapts are cleared, some units will function normally right away while others must learn how to shift properly. The replacement unit had the exact same shifting problems, so we had the vehicle taken to the Mitsubishi dealer to have the shift-adapts cleared. After attempting a cleaning of the MAF sensor and trying to tweak the TPS adjustment without favorable results, we sent the installer a replacement transmission. The tech had performed the shift-adapts clearing procedure prior to calling in the claim. The installing shop had a new, aftermarket, top-of-the-line scan tool that had a function test for clearing shift adapts. Only a factory scan tool can guarantee results every time.Īs an example, we had a 2005 Mitsubishi Montero with a fresh reman unit installed that had a 1-2 shift flare and a harsh 2-3 shift. There are many aftermarket scan tools that have adapt-clearing functions, but the results are not always effective. Often an OE factory scan tool is required. A few years ago, disconnecting the battery would clear the shift-adapts in most vehicles, but this is no longer the case. Any time a transmission is rebuilt or replaced, the shift-adapts must be cleared. When a unit is failing, the PCM/TCM will be constantly trying to compensate for the slipping or harsh shifts produced by internal unit failure. Shift adapt strategies have been common for well over a decade now. For that reason, the latest updates should always be installed when a replacement transmission is being installed.

Where it gets tricky is when the factory doesn’t publish an update on a TSB to notify technicians that a change has been made.

It just makes sense that the OEM software may not operate the transmission as originally intended, and adjustments have to be made to correct problems.
Hands down, updating PCM/TCM software corrects more problems than anything else. Software updates, clearing shift-adapts, and performing relearn procedures
