Well Ron I just got done researing this and found some good info, might want to check this out. 42RE shifting solutions by Greg Montero. Apparently there is an electrical governer switch just above the park lock external that cotrols presure and speed somehow

I don't know that this will help your reverse thing but it may help me and others. One more thing I lost the speedo in the jeep now that the tcase is back in I tried 2 different ones at the tcase still nothing

It is raining today so I am goint to play Betty Crocker and make some yum yum's I am getting sick of the jeep :wave: Doug
