Going to go to a few PNP's this weekend looking for speedometer sensor driven gears. It would help if you could tell me what other GM cars have the TH125c automatic. If you could include the years of the models, that would help me narrow down the search. The goal is to get at least 2-3 driven gears of various teeth.
Thanks, Kit

Tons of 'em! Cavaliers, Beretta/Corsica, even Celebrity/6000/Ciera in the earlier years. Citation... The list is long.

Early Buick Century had the 125 as well.

Thanks for the replies. I went to local PNP but was not successful. Most of the GM cars there were from the late 80 on up and all of them had the newer speedometer sensor that is the barrel or can type, not gear driven. Will have to keep searching.
Thanks, Kit

Thanks for the car-part link.
I went to the Commercial Ave PNP this morning and was able to get two different driven gears.
I got a 29 tooth and a 30 tooth gear. I just installed the 29 toother and now the speedo is reading only 2-3 mph less. (than what I'm actually doing) It was reading a good 7-8 mph less than actual mph. I'm going to leave the 29 tooth gear in there for now BUT I would like to try one more tooth less. (28 teeth/ yellow)
Thanks, Kit
