As I mentioned in an earlier post I gave the neighbor kid our 1988 9000Turbo for colleage and within weeks he calls saying the transmission died. I'm skeptical now that I heard the facts.

He is in automotive mechanics school so hopefully his skills of observation are solid.

Note: this transmission always had the hard clunk in first and the "slip" from 4 to 3. So he has the fear it was going to die.

He told me at a light it never wanted to go. No matter what gear he cannot get it to go over 25mph in any gear. Didn't mention much about hard shifting or such. He then said he put TWO quarts of AFT in it to get it up to level. This car has NEVER used ATF fluid, I replaced a leaking lower ATF radiator last summer to.

For it to take two quarts I assume it's either leaking from the system (he observes it is not but I'm going to send him back out today again to look) or that the AFT is going into the coolant system. I would assume that the AT system has higher pressure so the AT would push into the coolant more then the coolant into the AT.

Here are a couple of questions:
Does a 1988 have the ablity to fail in the coolant/ATF mix failure I read about with the coolant radiator going bad?
Does the fact it only does 20mph at 5K rpm tell you that there is some residual (or contaminated) fluid in the systme and not a failure of gears or valve body?

I'm trying to get ideas as his dad is already shopping for a used tranmission and I don't want to see him jump the gun if we just need a radiator and a some flushes of each system!

Lastly is it true that the slipping 4/3 and hard shift into D the first time can often be fixed with couple of seals being replaced under the service cover of the AT?

Thanks!
