I'm going to buy a used automatic transmission, so my MKII would at least run. I was wondering would the MKIII automatic tranny fit on MKII's? Are there any conversions I gotta do?

Thanx guys for any help you can provide.

What year is your MKII????

There are 3 different tranny's that we're talking about here in this subject.

The 82's have the A43DL, which is not a electronically controlled tranny.

The 83 - 86's have the A43DE which is a electronically controlled tranny.

The 86.5 - 92 (US spec) MKIII's (both the NA & turbo) used the A340E tranny. Don't know of anyone who is running a A340E in their MKII, unless it was a 7M conversion.

My MKII is a 85, and has the A43DE and has a 6MGE block/head. Do you know if I can switch stuff around from my A43DE to the A340E so it would be compatible?

Thanx

Welp, that's the question that I would like to know also. I don't know of anyone that has tried this yet. Many peeps wanting to ditch their A43Dx for a W58 5-speed, but swapping Auto A43DE's for a A340E (even temporarily)..... :oops: Wish I had a better answer. :oops: I "think" the size dimension (lengthwise) is different, but don't quote me on this.

Others???????

You can swap them and it will work, but the MkIII transmission is semi-electronic so the overdrive won't function. You could probably find some way to install the MkIII ECT at the same time, but I don't know anyone who's tried this.

isn't it that the 85 MK2 w/ A43DE tranny is also a semi-automatic tranny as well as a A43OE from a MK3... have to check on that if it is compatible on the tranny book
