Thanks Jim. Finally I read the test procedure correct. On the SML they show doing the test at the control valve. I mixed the lines coming and going up though, so it didn't make good sense. Vacuum should be @ 350mb at idle w/ throttle off, and 0 at full throttle. I was concerned that the ADA may be position critical since it had a paint mark on the swivel nut. But than, it could not affect the tranny what so ever.

The vacuum valve on the IP is intended to roughly simulate the effect of gasser manifold vacuum (with throttle) for feeding to the tranny. It's adjustable over a range, too. > Can I test the line without removing the intake crossover ? If I put a > Mityvac on the modulator end of the line, shouldn't it hold vacuum at > throttle off ? Yes. But make sure you're on the tranny line and not the one that goes first to the IP, it has a controlled (and throttle-position-sensitive) bleed on it. You may have knocked a line off elsewhere that due to the natural restrictions of small-diameter line has resulted in a lessening of the vacuum supply in the car, but not enough to disable anything. That would throw the calibration of the IP dingus off. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
