Transmission shop recommendations in Minneapolis?

Valve body problems are fairly typical on these transmissions. You have higher mileage so unclear if you could actually get away with a valve body. Depends on how burned up the fluid is and how much debris was in the pan. The debris in the pan can be subjective as well. Unless you have a picture to share it is hard to convey what the pan debris looks like.

Not sure how these guys ship and what shipping costs may be, it may be factored into the trans price??

They probably have the best handle on the valve body upgrades.

I know if you end up going through the dealer, you get a 3-year 100,000 mile warranty.... But you'll have to compare their price to make a decision. You'd also want to ask about an aftermarket torque converter, if that would affect the warranty.

I thought I would add that when I looked up the feedback and reviews for my local Chevy dealers, it was pretty poor when it came to the service departments. I know people tend to leave the bad stuff more than the good but, nobody was leaving any good feedback regarding service departments. However, there was a lot of good feedback on the sales and finance end.

I'm attaching a picture of the pan debris just for reference. I've since been told that the converter did come apart internally and take out the pump and pretty much everything else. The filter was clearly plugged too. I had it redone with a billet converter, upgraded valve body, and some additional stuff. The place I had do it says they have done hundereds of the 6l80s. Hopefully they did a good job.

Yup that pan debris is a pretty bad indicator of a bad failure that will need a full rebuild. Once the shavings are above the super fine particles, then you are into the big money.

Sounds like your shop did a pretty good update with the billet converter and valve body, but you might check with them and see if they did any TCM tuning as well to keep the problem from reoccurring if you plan on keeping the vehicle for a while.
