When swapping speedometers do you have to change the little meshed gear inside the transmission tail housing if you go from an 85 mph to 140 mph. I just put in a new Tranny and had to change it since the 700 R4 was out of a caprice with a diff. trans. but now I want the bigger speedo since I bury the 85 twice a day. thanx.

I didn't have any trouble with it, I swapped the entire speedo and it reads perfect. This is an a camaro, but should be the same with a firebird
