i need a speedo gear. please help me lol.
i need a to replace the speedo gear in my T5, went to the dealership and they have no idea wich one I need, i need ot tell them how many teeth it has etc. etc.
So i ask all of you, how many teeth would a speedo gear have for a 3.23 rear end & 255/50/16 size tires, I honestly dont even care if it's a bit off, I'm just sick of this thing throwing a vss code and running in home limp mode.

2.73's had 17/37, as for 3.23's just call different dealers and eventually you will find one that knows what they are talking about. I had to call 4 different ones before I finally got a competant parts guy.

I appologize if I'm a bi tharsh here, but why don't you just pull the gears out and conut them? If you just need a replacement, it's just that simple! Even if you have a wear issue (sounds like you do), there should be enough left to be able to count. If you want to get pretty darn close, I have the info you need, let me know!

I can do speedometer gear calculations and find you the best gears possible. The only problem is, I don't know what gears are availalbe for the T-5. All my research gives me gears for the Ford T5, but I can't find anything for the GM T5. If someone can tell me the gears available (number of teeth is all that is needed) I can calculate anything you need.

23/9 would be a pretty darn close combo of gears for him IMO.

If it's a T-5 car, you need a 7-tooth drive gear and a 19-tooth driven. It actually works out to 7 and about 18.55, but you can't exactly buy one like that... 19 will have to do.
