I just bought a 2000 1500 with a 360 cid, and an 46rfe automatic transmission. I have read a lot of posts about slippery trans or lack of power or trans shifts irratically. There is a TSB on alldata and on Chrysler's corporate webpage pertaining to the 46rfe transmission. The TSB refers to flashing the PCM to correct the irratic shifting. I had this flash done about two weeks ago and it helped the problem out. But just yester day I had the transmission services and the bands adjusted, and now the irratic shifting has returned. What I'm getting at is that the problem may not be in the trans for most people, but rather with the engine. There is another thread on adjusting the TPS and I'm going to give that a try. Just to let you all know whats up.
