I am trying to get my act together to rebuild my Gear Vendors and get it in the truck.

I have 3:54 ring and pinion, what speedo gear are you guys running in the GV?

I'm hoping all you guys from other forums will chime in too.

thanks,
mark

Glad to se you got got it rebuilt....was it hard?
I think i still now were my paper work is hang on ald i will see if i can answer that!

mhuppertz

I haven't rebuilt it yet, just getting ready too. The Gear Vendoes people tried to scare me into not doing it and giving them $700 to do it.
I am a little nervous about trying to rebuild a trans without a service manual, but GV didn't want to part with one, so I am going to make educated guesses based on the AT's I have destroyed, I mean rebuilt!

Thanks Flash!
by the way, the only thing I don't like about the GV unit is the fact that it uses a "brand x" turbohydro speedo drive and gear....

flashgordon

How tall are your tires!

mhuppertz

They are 33"

flashgordon

You need a 36 tooth gear.........don't get it from mopar tho, it a GM gear and housing.

Dus you truck have the gear reducer on it now?.....were it gos into the transfercase?

mhuppertz

Yes, I have the gear reducer. I'm not sure if I still need it or not?????

flashgordon

Acording to GV manule the 36 is with 1.11 multiplier

there is allso a eng rpm math that thay us that i will send you next....just becuse

mhuppertz

Thanks man! Now I just need a PDF of a service manual!!!

flashgordon

method of determing correct drive gear
1 multiply engine RMP in direct drive by .015

EXAMPLE:4:10 gearatio with 31 inch tires corect driven gear =2667 rpm times .015=40 tooth

Early modes GV p-type overdraves were equipped with a 17 tooth dive gear and are uiltiplied buy .017
This model can be distinguished by the 2 o'clock position of the speedo housing hold-down bolt.


Hope this made sence and helps!

flashgordon

Ya and if you ever do! send it my way to!!!!!

I would bet that thay have one on there sight for the certified installer around the nation.....just need to find that magicle internet address......

mhuppertz

Looks like mine is the old type. I hope that's not bad!
I just pestered them again about a manual......

Mcmopar

Those GV's are nice units.

flashgordon

What you should do is bs them into beleving your going to be a installer in your area....or maybe you now of a trannny shop that could help you to bs you way into getting them into being an installer shop, then get the
manule web sight!

Good luck!

Mcmopar, i agree, only have had mine for several month's but still think it's a grate unit,High priced,but still worth it. that first step $$$ is hard to do!

mhuppertz

I called Gear Vendors again today and they said they won't even sell the parts! I have no choice but to pay the $750
