Needing a 45 tooth driven gear for a 700r tranny with electric speedo. Anybody know where to get one. They are tough to find.

They have them

 

They do not have the 45 tooth for the electronic speedo. Just called them.

 

Does anyone know any other applications/vehicles that this GM 45 tooth, driven speedo gear was used in? Perhaps I could pull one from a junkyard blown Tranny. One photo is of the gear and the other is the speed sensor it mounts to.

 

I don't recall seeing a PN for one and was under the impression the cars that might have got a 45 tooth in mech. speedo years got a 44 in all cases.

You could make one.

 

Part number is 25513052.

 

Berlinetta's used them in 84 & 86 in some automatics. ( could be 85 too, but I couldn't find a reference to that gear anywhere in the 85 gear charts ) I'm not POSITIVE that the same gear will fit on the 84-89 style VSS as well as the 90-92 VSS simply because I've never personally placed that gear on both VSS's,..... but the part numbers book shows the 84 & 86 Berlinetta used a 45 tooth Driven gear with that part number.

 

Thanks for the info! Was that the 700R4? I know Corvette used the gear in some of the C4's. It is a GM part so I'm thinking it may have been used in other GM cars outside of the Camaro/Firebird family.

 

Yup, 700R4. The same 84-89 VSS used in the Berlinetta (and 86-89 Firebird ) was also used in the Corvette from the same era, so I'm guessing that the Vett 45 tooth electronic gear you mentioned "should" be compatable.

I check my spare parts, but didn't have one available. Good luck on the hunt !

 

Thank you for your input. It's a tough one to locate.

 

Found it!
