History - 94 Z28 83,000 miles, Transgo stage 3 and tranny cooler at 52,000 miles. Computer reprogrammed for shift kit. All bolt-on's.

Today, I went WOT, and something weird happened. When it was supposed to shift into second, it slipped really bad. I had to let out of it for it to shift. When the tranny finally engaged 2nd, it squealed for a second. I knew what happened, so I layed off the car for the rest of the drive. Part throttle shifts seemed normal.
After running my to the doctors office, I got in to go home. Again, everything was ok with normal driving. So, I wanted to be sure that what happened earlier was repeatable. I turned a corner, floored it, and it slipped in first gear this time, shifted to second and slipped also, then squealed when I let out of the gas. Now part throttle shifts are very, very firm!
Upon getting home, I checked the fluid level. It was a little past full, and the fluid was very clean and light pink. No burnt smell YET!

So am I in for a rebuild? If so, where is the best deal on a rebuilt one online? Or is that not the best solution? This car is used to just get me to work and back now days because the drag strip here sucks *****. So I don't need anything extravagant. Just a factory rebuild with design problems fixed.

 

The same stuff is happening to mine,my tranny expert told me on the phone that it could be the solenoids.

I am going to change the fluid and filter and check the pan for clutch material.

He also suggested getting the codes read,sometimes they are hidden

 

Anyone else?

 

The only solution to my 4L60E woes behind my 396 was a T-56

 

Post this while stuck on the toilet?
