ZF transmissions bellhousing interchange

[pcmenten]

Anybody familiar with ZF transmissions?

I have a ZF 4HP22 that was attached to a Rover 4.0. The bellhousing is removable. I was just curious to know if other ZF transmissions would fit up to that bellhousing.

The only trans that will fit that bell housing are the 4HP22 and 4HP24 Paul.
The bell housing for the 22 is smaller due to a smaller diameter torque converter.
The 24 is a stronger trans rated @ 330ftlbs torque while the 22 is 260 ftlbs.
The 24 however is an electronic trans so you would need to provide a method of control for it.
Or just swap out the 24 internals into a 22 case.
Mods are available to gain more strength if needed, thanks to the BMW crowd.
While the ZF in the landrover was a 4WD configuration, it was also used in Austin, BMW, Jaguar, Lincoln, Mercedes, Volvo, Peugeot and some Chevy imports as a rear wheel drive trans.

Hope that's helpfull.

Cheers

Thanks, Fred, very helpful.

I saw that ZF made 5 and 6 speed transmissions, but the trans-to-bellhousing bolt patterns look different. If I use my ZF 4HP22, I'll probably get the output shaft and tailhousing from a 2WD tranny like the Volvo and swap it over.
