Hello all of you.
I have zf 4hp22 which came from a jaguar. i changed the bell housing to rover type.
but there is no speedo gear on the transmission.
is it possible to convert it to mechanical speedo gear ? Or does any zf 4hp22 come with mechanical speedo gear?

The RV8 LDV van came with a mechanical speedo, but those boxes are getting rare now. It is possible to convert using a BW35 speedo gear and sleeve as someone on here did it.

Have a word with Andy (eightofthem on here) as he's got a good knowledge of the ZF box and may know other ways to get the same result.
 
If it’s a hall sensor on the gearbox I’m working on something at the moment for a client. Looking to developing a device that will read the signal from the sensor and drive a stepper motor for the mechanical speedo. It’ll take me a while to develop it and you may want to find a more reliable option.
