Since Manny has kinda retired from the TH425 rebuild business, we in the upper midwest have found a rebuilder that has done an excellent job of rebuilding for us.

The fella's name is Steve Turnquest. His company name is Transformation Performance Transmissions Inc. and is from Ramsey Mn. NW of Minneapolis. He builds transmissions of all brands but specializes in heavy duty and performance. He has attended our local GMC chapter (Greater Midwest Classics) work rally and did a session for us on building the TH425 for heavy duty use. He puts in "heavy duty parts" which can up the price. Last trans I had done by him was in the $800 range. Depending on what yours needs, it could run more. He has actually sought out, through his sources, OEM parts that he stocks for the 425, but does not have "everything". He has quite a few TH425's out there now with no come backs.

Don't know if he will ship to other parts of the country. You could ask. We drop a trans off and it is ready in a week to pickup.

HTH someone.

By better, do you mean cheaper, or higher quality? Often times, the words
are NOT INTERCHANGABLE.
Some of us paid our own way through trade schools and served
apprenticeships at 50% of Journeymans scale to learn our trades. Our ROI is
very low, sometimes taking 10 plus years to become proficient enough at our
trades to allow us to make a living wage.
If you investigate your transmission guy very much, you will probably
find a lone duck, hard worker, with a lease to pay, sometimes employees
that need paid, suppliers and vendors that like their bills to be paid,
utilities, you name it.
Please consider this too when making statements about what a person is
worth.
Just saying that I have walked in those shoes for years, and have some
insight.
