Auto gearbox swapping

Hi Everyone,

The auto box in my 480 turbo is slipping, I can find an auto ES, but I am afraid the swapping can't be strait forward, the turbo engine seems bigger than ES engine and the location of the linkages may different. Anyone has any experiences of swapping the auto boxes?

Thank you.

Hi,

first of al,how old is the oil in the gearbox ?
Is the gearbox leaking much oil ?

Does the oil smell burned ?

-->new oil

ItÂ´s no problem to exchange the gearboxes of the 480!

The 480 had three standard types of ZF boxes which you can exchange easyily, no problem,everything will work fine.

Good luck

Dan

3 possible solutions from cheap to "less cheap":

1 - As said before, first change oil. If that doesn't work, look in your wallet .... then look on the type-plate of the auto box for the ZF type number and ...

2 - Try to find an identical one from the scrap yard. If you are lucky you can find one with low milage. They are scarce, and therefore costly (in NL nearly the price of a revised one ....) Check is the speed sensor and its position in the box are exactly identical to your current one!

3 - Or get the box revised by a revision specialist (preferred and most expensive solution)

Besides the costs of the box, take into account the hours/costs for work. For my turbo it took a experienced mechanic almost half a day and lots of @#$%^&* (tip: lower the subframe) The difficulty is to mount the heavy box exactly in position before mountin it on the engine (do not forget the tolerance-rings (no idea if this word exists in english .... but if you mount the box without this you'll wreck it!)

You can change auto gearboxes their shape are all the same (ZF 4HP14).
But if you have Turbo engine you must fit Turbo or 2.0L auto box!
An 1.7L ES box was designed for smaller torque, many parts are weaker
eg. torque converter, valve block, pistons (my dealer told me), perhaps brake bands and clutches too.
