Anyone know if this is an easy swap? - The ratios are not exactly the same but that isn't a big issue. Are the ancilliary connections (kickdown cable, vacuum line, oil cooler etc.) the same ? And perhaps crucially is the Drive Shaft (inside the TT) the same? I wouldn't ask the last question but the relevant part of the WSM is with the subject car across the sea at the moment.

Edited as the donor car just got 2 years younger

Jon;

Going from poor memory here...

The only thing I remember is the kickdown cable. And even that may be afro-aussie engineered.

Thanks Scott

We have since discovered that the bell housing with the TC in it is about 20mm larger diameter. This can be cured with a FBH.

We also discovered that the donor box is an '89!

Next question - Inspecting the wiring the '89 box has additional wiring for the ATF fluid temp sensor (only
connects to digidash cars so can be ignored) and wiring to what is referred
to in the WSM as transmission protection switch (WSM page 37-158). Anyone
know what this does ? It looks like some form of pressure release valve? On
pre '87 models there is no electrical connection to this part just a
threaded plug but both pre and post '87 appear to have the hydraulic
pressure relief valve inside the box.

Hi I think the crossmembers are different different exhaust locators and possibly trans mount points???? and the axle loxcation is as well I think the early trans had the axle located more to the front, later model moved 20 mm to the rear???"?or visa versa

What you may not like is the 89 ALWAYS starts out in second gear...
