A4LD into SE6b - is it worth doing?

Cheers Andy - I wasn't sure what version was used on MBs but was aware there are several flavours of A4LD(e/E) but didn't know of the two versions of pre-e gearbox.

One other ID for the later A4LDE box... It has a multipin socket on the side. That gearbox then became the 4R44 and the 5R55 before being discontinued.

Just got in touch with the first owner of my MB (co-incidence ) and he says he had a lot of GB trouble until the engine and GB were replaced at 200k in 97 with the then latest Ford parts after which he had no further problems.

The Swiss Middlebridge had a transplant from a late Scorpio. It is the only one as far as I know that runs O2 sensors and a CAT.

If looking for a non electric box from a Granada then go for later than 92. Boxes I've seen before that have well worn bronze thrust washers. Later ones Torrington bearings.
A Cosworth box is worth having as they are built stronger. I think the box went to 800nm torque from 550 originally.
The good thing is a lot of the later mechanical guts can be incorporated into a hydraulic box during a rebuild. A better oil cooler and inline filter should be added at the same time as fitting. Adding a drain plug on the sump is also worthwhile !

This was the gearbox in one form or another fitted to the Ford Explorer at the time therefore plenty info on the Explorer forums. Also still well supported spares wise in the US.
Oregon Transmission has everything you need. With the "global sales" thing on fleabay fairly easy to get.

I was under the (possibly mistaken) impression that Torringtons were not fitted until the early 4R44 boxes which are all ECU controlled? There is a rebuild thread on the Explorer forums where some of the later bits were retro fitted to an earlier box. However, for the 2.8i Engine and earlier 2.9i, the only gearbox that will do is one of the first two iterations, before the three pin TCC socket. Unless you want to design a standalone transmission ECU anyway.

My MB had a Cosworth box which was replaced in Germany where the PO was working - he later found the gearbox was ok so its now my spare ( sorry not for sale ).

AJL you might be right as the boxes I done were a mix of original and Ford warranty replacements. Back in the 90's I knew one Granada owner that had four fitted by Ford in two years!
I do know there are several flavours of the basic A4LD box. I've had them side by side on the bench. Some have bearings in place of bronze. The latest thrust just behind the pump housing is now plastic.
The Cosworth boxes had torringtons in places although not as many as the last Cosworths from the frog.
I have a bunch of the later fives which are future spares source so now I'm playing with Microsquirt to control them.
It's still an easy box to rebuild and incorporate a bunch of improvements which should make it good for 200k miles in a 2.8 or 2.9.
