Hello Group,
I just had my 84 300SD in the shop for a plethora of things and one of them was the transmission shifts really hard, especially when cold..Barks the tires in fact from 1-2 and the rear end clunks from 3-4. The owner of the shop told me the "vacuum control valve" on the injector pump is inoperative and they wanted $200+ to replace..Being already at 1000.00 in repairs it had to wait..Is this an easy part to change and is it expensive? Is it the same device that shuts the car off? What can I screw up doing it myself? Thanks all for your help! John
