5 Speed TOP STARTER Gearbox for EA71 engine, with 3.7(10-37)CWP

Featured Replies

I would like to know the code of the gearbox as the title,as well as in what cars was standard equipment.

In my service manual it calls them "5GM" , but I think you are asking for the production code which would be on a foil sticker on the transmission by the bell housing. Sound correct?

 

Info you may or may not need:

1st gear 3.666

2nd gear 2.157

3rd gear 1.464

4th gear 1.029

5th gear 0.789

thanks moosens.

only this 5speed gearbox is equipped with the 3.7 ???

what other models are equipped with 5speed with 3.7 CWP ????

the "5GM" is sticked on the gearbox ???

where exactly on the bellhousing is appeared the code ???

this one,you mentioned above,came from what model ???

Only the "FE" model here in the USA came with 3.70 as best as I can tell. The other five speed were 3.90 or 3.889 to be exact.

 

Here the FE was a fuel efficient model with higher compression , different cam , and a taller 2nd and 5th gear in them. Perhaps you have a similar model?

 

The small foil sticker is located at the side/top of the bel of the transmission. I have seen various editions but they all begin with T. When I dig up a parts manual I will have more info for you.

 

That code 5GM is simply used to express a five gear manual. The true production code which identifies specifics is in that sticker.

 

What model is the car this tranny is from?

 

I have most of my manuals in storage. I will try to help but hopefully someone else has them handy.

I would like to "build"some 5GM with 3.7 for competition use.

This is the reason I am looking to find the right 5GM one.

I wonder if an EA81 or EA82 FWD Turbo would help you for the final drive. They are a small percentage of turbos of course. But you will find more of them than EA71 transmissions from an FE.
