Jeff,

Agree about not knowing the condition of the tranny. I bought mine with 50,000 km on the clock as an Approved Used Car from a dealer with full service history. Have maintained the car as new since. When I first had the tranny serviced the ATF looked like new. I also forgot to mention that I always replace the filter when I have the fluid changed. The clean ATF rule is a good one to remember.

Understand your reluctance and the idea about putting the car on four stands makes me think twice as well.

Don't know if Getrag units were made by ZF or not.
