No, the car runs fine it just won't shift into 5th gear. I've been over everything reguarding the HGS and the MAS. The MAS gets the load signal from the EZL and tells the transmission to shift into 5th gear...so you have the RPM signal, Load and position of the switch on the shifter.

The EZL has two codes one of them is for the map sensor or load sensor which is fixed at this point. It should change with the removal of the vacume line.

Anyway back to the question. Does anyone know if an EZL from a car other then a 90 300SL will work?

Thanks guys.
