What 4WD auto boxes bolt up to EA81?

Post by Craigus » Thu Aug 03, 2006 9:09 pm

My brother in law is looking to do a manual to auto conversion on a Brumby for an elderly friend. He wants to retain 4WD capability.

I found some posts on the USMB that indicate that the L series 4WD auto is a direct bolt - up. Is this correct?

Yes it is however the MY series had a bigger transmission tunnel if they where automatic so some massaging of the tunnel may need to be done

or fit a lift kit - will solve all your clearance issues :)

a lift kit for the elderly ? not a bad idea. measure 'em up so they don't have to climb up or lower themselves into modded MY.

The bellhousing patterns are the same EA81 to EA82 manuals anyway.

The distance from bellhousing to rear diff also within specs to a don't matter degree.

The splines of the front drive stubs may need to be compared (as a consideration)

You could actually make up half a lift kit, ie: 1 inch engine and gearbox spacers, shouldn't effect clearance but should be enough to fit the box into the tunnel, also it would reduce the cv angle in theory making them last longer.

I have an MY 3 spd 4WD auto you can have, everything including interior, torque converter, tailshaft and matching diff are all yours if you just get it out of my way. The only thing missing is the is the metal plate the holds the torque converter to the crank.

Baron's suggestion is very similar to my own, the 1" spacers do help out a lot, mainly in the suspension department. You can say goodbye to positive camber!
However a guy I know said something to me the other day about running CV's on a flat angle. The wear point is concentrated, meaning they flog out quicker. This is not my experience, but it is a good point.


Another point, might be relevant might not be. My 1980 sedan that was factory fitted with an EA81 and 3spd auto had heaps of vaccuum hoses and diaphragms hanging off the side of its little Hitachi carby. A few of these looked gearbox related, although its been a while since I looked at them. Kickdown related maybe?
