Im looking into buying a 95 Z28 with 85xxx miles on it. It has a shift kit, and a tune. The tranny shifts fine when normally driving, but once you floor it, it just revs up to red line, and doesnt move any faster. It is disconnecting for some reason. Any ideas on what it could be, and how major of a fix it is?

Might just be low fluid.

So low fluid would cause the tranny to totally disconnect at WOT? If not that, what else could it possibly be?

If there's not enough line pressure at high rpm due to low fluid the shift could be delayed.

ah. that makes sense. Im gonna check the car out again (throughly this time) and ill post what i found out.

If it isnt the low fluid, what could it be (I dont want to buy it and find out the trans is bombed...)

the trans is going bad I had the same problem, I was able to fix my problem temporarily, by having the trans flushed, and adding lucas trans fix. I believe the new fluid, and modifier swelled the clutches making them stick better, and thus shift, instead of slipping and causing redline, and rev limiter.....hope this helps, mine still works good 3k later.

my 94' had that problem way back when. all fluids checked out okay which means the tranny was toast.
