I just bought this truck a couple of weeks ago and have changed all fluids (motor oil, tranfer case, front diff, rear diff, ect) except for the transmission. I wanted to get some advice from you experts on this issue before I pull the pan.
At light throttle it shifts fine through all gears (but a little too smooth and long for me since I don't like the clutch disc sacrifice involved with slow/smooth shifts).
But at about 1/2 throttle the 1-2 shift is really slow. It seems like the normal slow/smooth shift you would expect from the factory but then it still has no definite feel of engagement for another ~1/4 second. It's like the first delay of time is being used to fill the accumulator, then more time for the apply piston to close the clearance in clutch pack.
3-4 shift is also really slow at 1/2 throttle.
Converter lock speed seems about normal (too slow for me of course).
I get the same issues at WOT but I've only tried that once because I don't wont to do any major clutch disc damage until I get this issue resolved.
My question is what is the best way to limit this shift delay time - short of a rebuild (I'd hate to go into a fully funtioning tranny when I can get another several thousand miles out of it if I treat it right)? I really can't afford a rebuild but...
BTW, the 4l60e I built for my Trans Am in 2005 with directions on here from Crosley in this thread is still alive and barking tires after several 1/4 mile passes and several thousand road miles. Thanks Crosley!!!
