Took the TB yesterday to get transmission fluid changed, Fluid was low and had lots of carbon.
They tore it apart to look for damage, did't think it would be to bad cause tran has been running great.
Got call today complete rebuild is needed $2200 :pale:
It's my fault I didn't get it done sooner.

90k miles plus on my 2004 TB... haven't changed the transmission fluid yet. I guess its a failure waiting to happen... but its not in the cards right now.

Do you know for a fact it's bad or is the shop trying to make a few bucks off you and just "tell" you that it's bad??

This. There's a point where if you don't keep up on regular trans maintenance, you might as well just skip it until it fails.


I'd have flushed it and driven it before anything to see if there was a drivability issue. At least then you could start saving up for the inevitable replacement.

I learned this lesson very well on my last vehicle. Sometimes it just sucks to try to take care of something that you think you are doing the right thing...

I disagree with the old "don't flush it, it's too far gone" theory... The stuff I was reading when I was an SAE member (and had access to the documents) leads me to believe that it's not the act of doing the flush and the new fluid freeing up all kinds of crap in the transmission that causes it to fail... It's that this plugs the filter and starves the transmission of fluid, which THEN tears stuff up...

You're supposed to do the flush, THEN a week or 2 later, drop the pan, change the filter, and top off... I did this with an S-10 Blazer that I had, and everything was fine... It had 180,000 miles on it, and had never had the trans touched (I bought it from a friend, who had it as his high school/college vehicle, and his parents bought it new)... It towed a 5000# boat down to the lake most weekends in the summer, for the first 100k of its life; then my friend's brother had it, and then he had it. It got a rust hole in the tank, and it sat for 4 years. I bought it from him, non-running, for $200. The transmission fluid looked like black oil, and smelled horrible.

I dropped the pan and changed the filter, then did a full "flush" (pouring fluid in while idling, with the cooler line off, until new fluid is seen coming out), then drove it for a week or 2, then dropped the pan and did the filter again... It ran fine for the 20k that I put on it before I sold it...

What was wrong with the parts?

This sounds like a classic example of the shop going too far without authorization. I'd tell them to put it back together and let me get a quote elsewhere because you didn't authorize them to take it apart yet.

They did ask to pull it apart, All repairs we approved before any work was done. Sorry I didn't detail everything to that extent in my first post. This is not random tranny shop I went to, My friends and family use the same shop. Could I have just had him closed it up? yes that option was givin. I just went ahead and got it fixed while I got the $$$$ instead of waiting and it going out on an Island, having to be towed off Island is expensive(big tow truck that can handle sand plus ferry $$). I does slow down the mods I wanted though.

1st & 2nd were about burnt up, the sun gear shell was almost stipped out, the drum had grooves in it and the band was just as bad, and most bushings were almost toast. I will try to get pics of some of the worn out parts when I pick it up today.
