My bf is having the same problem you are, won't go into 3rd, just revs. However, his transmission was just installed last June and was fine until about a month ago, when the shifting issues started.

After talking with the warranty dept, they are having us do a few things to see if it fixes it. The first was to replace afaulty wireon the VCM with a jumper wire that is supposed to prevent the connection from burning out. Ref: TSB 667103.

We bought the part, and found that the locations we were supposed to use for the replacement wire were already in use by different wires, so we couldn't use the jumper wire.

Second thing we're supposed to do is check the tranny oil pressure. To do this, I was told to remove the 7/16 pressure plug (RH on tranny) and attach and oil pressure gauge. At park/idle, it should be reading 55-65 psi. I am then to do a "brake torque" (hold brake and floor the gas pedal for a second or two). The pressure should jump to 120 psi or higher. If it doesn't get that high, then it's possible there is an internal leakor a bad solenoid on the bottom of the trans oil pan.

Now, most of this is greek to me, but the directions seem to be simple and straightforward. We're going to try this Saturday and I'll post our findings.

I just responded to your initial thread catintat. Looks like either the directions were wrong or you just misread them.
