Me too! I'm trying to keep up with the troubleshooting of our 700R's because later this Fall I'll do a filter change a would like to know all I can and what to look for. I'm still considering pulling the motor and tranny and spend the winter going over both.
LaurieB-Cool picture of the pair in the garage. Congrats on the second one.....looks like a great find.

Well, the bad news is that when they cracked the pan a big piece of the 2nd gear band was in the pan.....Cry

I told them to take their time on rebuilding it as I wouldn't be back to pick it up until the 15th. The better half would murder me if I emptied the bank account to get the 'vette back sooner Wink  I'll post back how it all turns out.

So the band is fried....that would kill 2nd and 4th, but you should still have 3rd. That's why I asked if it just stayed in 1st or not....if you wind it up, it would shift on into 3rd.
Hope they do ya a good job!Thumbs Up

Thanks for the update.  Sorry she needs more work than hoped for, but glad the problem was found and you'll be getting her back in a week or two.

Well, here's the latest as of today....
 
I learned that this isn't a 'vette case, but it had all of the 'vette parts; go figure....there is an "ear" missing on the case...must have been from installation. The guts on the 2nd gear band show the problem. They want to have it done by Tuesday so I can get it Wednesday in between work


Damaged 2-4 Band

That trans has had water in it. The friction material becoming unglued from the metal band, the rust on the band, and the condition of the valve body gaskets on the valve body confirm that. I hop they are going to completely disassemble it, and put all new rubber seals/frictions in. A new torque converter is also recommended.....
Water will eat away the adhesives used to bond friction materials to the steel clutch plates, and band. Since there is also a bonded clutch inside the torque converter, it needs to be replaced, also.Ouch

The case is broken....but it looks like a fresh break to me. Hard to confirm from the pic, tho.
Why do they say it is not a "Corvette" case?

It could have had water in it at one time....anything's possible. as for the case break, It was a pretty dirty looking break, so I didn't think it was something the shop did.
 
I have a new case, and a few mods are being done; the TV helper spring and a .032 restrictor plate in the accumulator for a firmer shift among them.
 
The car should be ready tomorrow.....Thumbs Up

Well, $1900.00 later, it was a pleasant experience.....

I had all the upgrades (shift kit, TV helper spring, etc) done to an '82 case. A new torque converter, new sun reaction shell ( I was worried about the shell that came out of the old trans ) along with the usual overhaul items.

This rebuilt trans is so amazing now; the shifts are almost non existent driving around town but they're right there when you "put the hammer down". All in all, a good outcome.

That's great to hear.  Not a bad price at all, and to have everything running so smoothly is terrific.  Here's to plenty of enjoyment!
