Pulled my tranny yesterday, it will be rebuilt this weekend. I tried everything that was suggested on the forum but nothing helped. When put into second gear by gearshift it does fine up to about 3,000 RPM then just slipps. This is kind of a long story but very interesting for those of you who like stories.

My daughter had a friend spend the night with her Saturday night. Sunday afternoon her dad came over to pick her up. My wife, best friend, and I were sitting outside talking about the options for the transmission. The little girs's dad walked up and started talking to us. He noticed the THM-350 overhaul manual in my hand and asked what was going on. When I told him he quickly said that the clutches are fried and the transmission needed to be rebuilt. From listening to him talk I could tell he knew what he was talking about. So, I asked him how he knew so much about automatic transmissions. His answer stunned me, he said "well I should know about them since I have owned and operated Aamco since 1984." (You know, Aamco the transmission place!) I told him that I had no idea he owned this business and asked how much he would chared me to rebuild it (since I know nothing about transmissions). He told me it would cost about $1,600 to get it rebuilt. I told him that I couldn't afford that and I would just have to follow directions and pray for the best. He then told me that I could bring it to his home shop Saturday and he would teach me to do it. WOW! He asked me what kit I was going to get and after I told him he said "just let me get the kit for you, I can get a better kit much cheaper". To shorten this long story a bit he is getting me everyting I need, shift kit, rebuild kit, redline racing clutches and band, and all races hardened for less than $250! On top of this he is going to teach me to rebuild the tranny for nothing in his shop where he has all the special tools to do it with. Just goes to show that it is always better to be lucky than good!

 

$1600 is a REDICULOUS quote for rebuilding a TH-350.

On the other hand, it is really nice of him to help you with the rebuild.

Let us know what you learn during the rebuild.

 

$1,600 for a rebuilt TH350? The last time I bought a rebuilt TH350 was about 20 years and it was about $300 out the door (I'm must be getting old ). I had to remove and install myself, but man I hope for that price it was for him to remove and install. Sounds like you have a better deal with his home shop. Are you going to get a new torque converter as well?

 

Man that's a lot. You can get a B&M from Jegs for $900.

The $1,600 was to drive the car into the shop and walk away. I have heard stories of people spending over $2,000 to get transmissions rebuilt around here, no one does it except Aamco and a few backyard mechanics who give you the 10 year or until it leaves my shop warranty. Been checking into the parts he said we would put in it against TCI and B&M transmissions out of Summit and Jegs. Things he is talking about putting into it will make it into one of those high performance transmissons they sell. The B&M kit was going to cost me $246.89 and I would be on my own with it. At least this way someone is there to teach me what to and not to do while doing it. New torque converter will come later after the engine is rebuilt, don't need higher stall right now.
