Hey guys wondering if someone might now a fix for my problem. About 1-3 per month the sport mode light begins to flash on my 01 Catera. The car stay's in 3rd gear and will not shift down or up. Probably because it sense's a fault and it is taking a safety/mechanical precaution. I ran the codes on her and got a P1700 manufacturer control error I beleive this error is sent from the TCM. Any help would be greatly appreciated. I have 45,XXX miles on the car, and don't want to waste money and time trying to find a solution please help thanks

It's located on the left side of the transmission behind the bellhousing.. It's where your shifter linkage connects to it.. It costs $105 from autozone... Changed mine last month.. Took me bout an hour..
