EA82T Gearbox Identification
Posted 31 July 2003 - 05:49 PM
Can anyone identify this gear box?
It came bolted to a later model Jap import engine, which had the spider manifold and a turbo shroud, so I guess it was from a Vortex.
It has 4 electrical connectors, of which I assume 1 is 'reverse' but not sure what the others do.
In addition how do I tell what ratio it is without pulling it apart?

I can't see the lever on the right side. If it's up high (transfer case)it's the pushbutton, if it's down low (diff lock) it's the constant box.

Neat trick huh?

Since it's from a Turbo car, it almost certainly has a 3.700:1 differential.
I don't think I've ever heard of an EA82T using anything but that ratio.

Any clues on the ratio othe than a guess at 3.7? I really don't want to put it in then find it is different. I could turn the input shaft and see what the rotation on the axle is, but I was hoping to be more accurate.....
Anyway big THANKS again :cool:

The RXs are 3.70. I've got one. If this is the same trans as the XT6 has, then its 3.90.
BUT...if this is a special trans...then its going to be 3.70. I am voting that its the same trans as found in the XT6 5spd FT4WD, so its 3.90.
All turbo EA82T manuals are 3.70. Everything else is 3.90, unless you are talking about autos. I have not a clue on auto rear diffs tho.
I wonder about the serial numbers that are on the trans...maybe we can all compare numbers?
Posted 03 August 2003 - 10:34 AM
Yep, could be 3.7 or 3.9, maybe you can tell by the part number?
Posted 14 August 2003 - 11:40 PM
Still haven't figured out if it's 3.9 or 3.7
Any idea what the electrical connectors are for?
There are 4
2. Diff lock??
