Very interesting considering that I was looking at both AAMCO and Cottmans to do my 4L80E in my 'burban.
Well, I took the Blazer to Cottman's against my better judgement. I rebuilt the 700r4 about 3-400 miles before that. For some reason, something dislodged and clogged a passage (pretty sure it was one of those little cone filters). It was pressurizing fluid in the oil pump, and it was just blowing by the front pump seal. Since I was in school and it was my DD, I didnt have time to rebuild it again. I figured a reputable tranny shop (heard nothing but good things) would be able to pinpoint the exact problem, cuse I was sure they would have seen similar problems before. And the shop was about 5 minutes from my house.
I went in and told them what the problem was and what I did in the past, and the guy said in his normal condicending tone "Well, thats why you should bring it to the pro's, you have no idea what you are doing, else you wouldnt be here now."
After their visual inspection, the guy called me back and said it needed a full rebuild, for the tune of 2k+. I said hell no. Then he tried to tell me it would be a lot more then just the inspection charge to reassemble. I again said no, Im not paying it. When I got to the shop, we haggleddown to $200 for the mechanics time, and I agreed that was fair. I had a tow truck pick up the Blazer, and I threw the tranny in my friends pickup.
When I was in the shop, I noticed the throttle valve assembly (the internal part) sitting on the mechanics work cart. I questioned to why it was out of the tranny, and he tried to say "Well, it is standard to remove it when you take out the tranny properly." That started another argument.
When I finally got everything to another shop (again, I didnt have time to do the work myself), I saw some bad stuff. Apparently, Cottman mechanic didnt diconnect said TV cable, and bent and twisted the TV spring contraption internally. Then said mechanic somehow broke the heads off of several of the bolts in the valve body. I just said F*** IT, ordered a rebuilt tranny from the dealer (I know, I didnt know better than, but a friend who workes the parts counter got me a deal). And lastly, they did not support the front of the engine when they removed the tranny like I specified, so the rear of the engine was being supported by my ignition module (which went bad a few weeks later)
That was about 4 years ago, and the Blazer has not or never will be in another shop, unless I am the one doing the work, or personally supervising 100% of the work done.
Bottom line, it is your truck and your tranny. Do not authorize another minute of labor on that. You will pick up the Blazer and its parts by your own means, adn you will pay for the labor that is already put into it.
