if you have an auto with 373... the correct gear would be purple. Red is for the Manual trans

Hahaha, its cool mang!!

373s = 21 tooth, 410s = 23 tooth

For auto's with 4.10's its actually a Jeep part you can get from a Jeep dealer, atleast for an AOD.

My car used to have an AOD and I have 4.10's.

You have a 5spd now?

Yeah, I had it swapped last spring. Its got a t5.
I hated the AOD and it was pretty much shot anyway.

Actually, with 3.73 the Red as I stated is good for 85-89 T-5, 90-93 takes a white 23 tooth.
