1st gear slip/shudder under heavy throttle only.
Recently purchased 95 BMW 540i with 193,340 miles. Trans operated correctly until performed basic fluid\ filter change. Had pan off over night, refilled with AMS-OIL ATF, 6 qts. Thought was full, fluid perking out fill hole. Drove and found to be slipping in drive. Raised back up and added another 3 qts ATF. Car now will very intermittently slip/shudder when accelerating from stop with light throttle. Under heavy full throttle, car will also intermittently slip from stop. I also noticed problem began to be more prominent when slowing to below 8 MPH then accelerating. Like the GM 4L60E slip bump in the C/K series trucks. I removed pan after initial fill to be sure there were no "metals" in pan or unplugged wires or missing filter O-ring, all was good. The trans goes into fail safe every time except when trans slips/shudders under light throttle. Any one out there have any help or input with this scenario? Thank You.
