Automatic gearbox for Z7X 775

[LPG]

My gearbox decided to break down the other day. Fine in revers but nothing or very little in forward gears.
I have then found a 4HP20 from a Laguna I. They have the same parts number esxept for the last digit.
Can i use the Laguna gearbox in the Espace if not why

I dont recognise your car code is this mk4 espace? The gearbox internals will be the same if wheel & tyre size are the same on both cars. If not then the diff ratios will be different. if it is a manual then may be the ratios will differ slightly. I doubt if there is a difference if it is just one no. out

Z7X is the motorcode for the old V6 (12v), which didn't use the 4HP20 but another gearbox (not sure which). It was used until modelyear 1999, I think. The 24v is L7X and it was mated to the 4HP20.
A 4HP20 from a Laguna probably won't fit - there are even two different versions of the 4HP20 used in the Espace, and it has to be the right one. These people might help:
