42RLE relearn road test procedure

[83rampage]

Ive just finishing a rebuild of a 42RLE in a 2003 Jeep liberty and Im hoping some of the transmission experts on here can help. Im wondering what is the best way to do the re-learn road test. I have an older Snap-on scanner Im assuming will be able to set the PCM re-learn, and if so, what is the procedure for the road test (drive it hard, drive it easy, etc??)?

And if the scanner wont do a relearn, is there a procedure to get this done? I ask this because I put a Transgo shift kit in it, and in the instructions it talks about putting the vehicle on jack stands and running up to 60 MPH slowly and slowly de-accellerating to a stop 70 times. It doesnt specify if this is after the PCM re-learn or if this is in lieu of a re-learn.

Just for reference the transmission was still in somewhat working order when I tore it apart. It was flaring going into OD, and the OD and 2/4 clutches were a bit burnt but not destroyed. It does have a new shift solenoid also and obviously the Transgo shift kit.

Any thoughts? Thanks in advance

Just to update this... So finally got the transmission together and back in over the weekend. Plugged in my Snap-on scanner and fortunately it was able to do a re-learn. It wasnt what I expected though. I had problems with my Toyota Tundra transmission a few years ago and the scanner did a reset and you had to drive it in very specific ways for the PCM to "re-learn" the shift patterns.

The scanner had "quick learn" as the option so I ran through the steps it gave me, and a road test wasnt required. You simply apply the brake and shift from park to neutral and finally drive. At that point the transmission did some funky stuff for a few seconds which I assume was applying all the clutches to learn the new clutch volumes and then it was done. Took it for a drive and all is working well.

Most mid to higher level scanners can do the quick-learn procedure. The 'road test' relearn I have not found a scanner that can touch that level of diagnostic's other than OEM. Unless it is a dealer doing an oem reman installation, everyone else will run a quick-learn procedure and send it on its way.
