I tried to change the filter once the box started to show
signs of slipping. I couldn't get one of the bolts out as it
was stripped so I had to run with new ATF and a dirty filter
for a week. The magnets in the oil pan had a fair covering
of particles.

The next weekend the tranny died while I was driving to my
girlfriend's house to change it! Drive in reverse but not
forwards. ATF is very dark and smells awful.

I can get a used auto box for 350GBP but will probably
spend 700GBP on a "kit" of conversion parts from a guy who
has done this job a few times before.

BTW not all ZF4HP22EH boxes are compatible with the car!
Boxes from L-Jet and Motronic cars differ. L-Jet boxes have
a kick down cable to the throtle body whilst Motronic boxes
have an electronic interface. My 1/85 Motronic 1.0 tranny
has an 8 pin connector but I'm told there are several versions.

Ah, a break from the Jim.C slagging and electric blower threads!
