rough shifting So cruising to school this morning after driving for probably 25 minutes i notice that my car starts shifting a lot rougher than normal. Instead of just sliding into the gears at part throttle it more or less pops into the next gear.
About five months ago i had the tranny redone with a 3400 fuddle, beast sunshell, z-pak, corvette servos, tranny cooler... the usual deal. and has never done this before.
i checked the fluid when i arrived and the level and color looked normal.
This is the only time its ever done this and im hoping it won't do it on my way home, but i thought i'd see what you guys thought.

There are many, many reasons for a 4l60E to begin to shift harshly and then not exhibit the symptoms again.
The PCM uses quite a few inputs to determine Line Pressure. I don't think that I would get too concerned about it unless it continues. It would be a good idea to get those cars scanned for DTC's, Pending DTC's or other useful info.

I've also been having the same problem. It comes and goes. 1-2 shift can be brutal sometimes.
I just posted this up today.

There a link in there to another thread which describes the problem completely and possibly what is causing it.
