Hi Todd,

The EH version is a very clever gearbox, and takes all kinds of information from the engine management system.

Do you have the engine AND the gearbox for the 4HP22EH? If you, it might be worth swapping them as a unit.

Best Regards,

Rob

Does the the 4hp22 require a different driveshaft? Does its computer run independently of the Motronic system? What electronic inputs does it receive from the engine? Can it be used with L-Jet?
Thanks,
Todd

Thanks for the info. TCD 17:23 12/16/2001 (0)
