Blown trans- auto TF999

I blew up my transmission in the snow today. Clanging and rattling and then smoking and fluid pouring out. It was an auto TF999. I don't have the time to replace it myself. About how much should I expect to pay for a replacement, installed, used or rebuilt. I can get a used one from $275 - $400.

I just blew out my 5 speed. Never replaced one, never done anything on the drivetrain, and a few buddies and me put in a used one in in 4 hours. Grab a Chiltons of Hayne's and you can do it with minimal tools. I would they a shop might charge you 700-800 if they did it.

If you're going to get a new one put in, I'd go with a rebuilt one rather than used. If you get a used one I'm not sure you're going to get a shop to put it in and have a warranty. I don't think a rebuilt will be much more than a few hundred more than a used one, the labor for removal and replacement will be about the same.

Rebuilt transmission around here cost about 500-800 depending on the model. And you can count on another 500-600 for labor at the going rate of around 80-100 dollars. If you can find a decent used one swap it in yourself! It should take around 4-5 hours. I did it just recently for my TF999. Used ones cost anywhere from 50-200 bucks.

I had my TF999 rebuilt 2 years ago. The tranny shop charged me $385 for the rebuild. That was with me pulling the tranny and dropping it off. That included a new torque converter. I will say that my tranny was actually shifting fine when I pulled it. The reason I had it rebuilt was that it was puking fluid when parked. This was also from a reputable shop that I had been dealing with for about 10 years.
