I just returned from a trip up to the Gurnee area where I met David West from Davids 4 Speeds. David buys, sells, trades, exchanges and rebuilds Muncie, T10 and ST10 4speed transmissions. The reason I met up with Davis was to sell him a used STIO that I had. I got what I feel is a fair price for a used STIO in good condition and a Pontiac aluminum bellhousing and the Pontiac flywheel. We actually pulled the side cover off the trans on the back of his Jeep Cherokee so he could look inside and he pointed out the things he would be looking for and all were good. On a scale of 1 to 10 he gave the trans I sold him an 8 and in nice condition,
David is a retired mechanic that has been doing 4speeds for 30 years. He was quite personable and suggested any time I was in the Milwaukee area to stop in and see his shop which he indicated is immaculate and is something I could tell he is quite proud of. If I make it up to Road America in the fall I will plan on stopping to visit David. If anyone else has any questions regarding GM 4 speeds or needs a first class rebuilt GM 4 Speed check out Davids website and some of his customers rides. I think he would be a good resource for anyone looking for a concourse quality 4 speed. If you know anyone else looking for a GM 4 speed pass on his web address, I am sure he would appreciate the referrals.
