I just replaced my tranny last month i went new from GM at a cost of 3250.00 (CDN) installed taxes extra. They wanted 3000.00 (CDN) for a rebuild installed taxes extra.
Total bill after they were finished was 3889.00 (CDN). Good Luck with yours willwren.

hes got an older 4t60, there are probably tons of rebuilt ones laying around. Will, if I were you I would start looking for one thats a good deal. You know its gonna happen, and you are better off to be prepared when it does.

I assume that it was covered under warrantee or you could have had a certified trani shop do it for a lot less.
What killed it :?:
If it wasn't covered under warranty, why didn't you go with an Intense bulletproofed and limited slipped for just a little more. :P .....about $2000. more cdn.

Did GM do any upgrading with the rebuild :?:

It wasn't covered under warrenty i tried for a goodwill offer but no dice. GM offered no upgrades with rebuild. As for going with the bulletproof for an extra 2000.00 cdn My bank account just wouldn't give up any more money it just kept laughing and laughing at me :P Keep in mind this was at a GM dealership, and they treated me great

What killed it :?:
They don't know, other than to say it was not driver abuse. When they opened it up they found busted teeth off of gears. I went brand new over the rebuild because i got 3 years 80,000 clicks warrenty.

I guess you are set for awhile. Our 2000 had a factory defect go wrong and we had to get a rebuilt for it, it cost like $5000 US or somewhere around there (I didnt see the bill). Be careful that you get it fixed, one part of the tranny doesnt get enough fluid due to a shrunked valve or seal or something.

Well isn't this interesting........I'm not usually a believer in 'mechanic in a can', but I've had a can of SeaFoam Trans-Tune rolling around in the trunk for a month. Since the flush didn't help, I figgered I didn't have much to lose. To err on the side of caution, I only used half the can.

By the time I hit the highway, the 1-2 shift was almost invisible, and the 2-3 and all downshifts improved over the next five minutes. Manually working all gears in a 5-10 minute period cleared it all up.

Not a final prognosis. Tomorrow morning in the cold will tell the final story, but my hopes are high. If this works, I'm going to add the other half pint, run it for a week, then drop the pan, change the filter, and swap 1/3 of the fluid. Looks like it MIGHT have been a stick valve body or other such crap.

One possible side-effect I'm afraid of is TC slip. We'll see tomorrow.

How'd you manually shift it? Playing with the linkages inside it, or running her up to high MPH?

You do know the shifter inside the gears, you should be smarter then that lol....

I'm thinking of doing a flush sometime this summer, should i maybe throw in a can of something like that before i drive to the shop?

you can manually do it on the shifting column or whatever its called, the PRND321 lever. He probably put his foot on the brake and ran it through the gears while the car wasnt moving.

Will, you just put the stuff in your transmission and run it for awhile, and then change the fluid, or can you leave it in there?

And you thought a mechanic in a can was worthless...

Hope it works for you Bill. Somehow I doubt it will do me any good when mine goes
