The GM made THM-4L30E automatic transmission in my 1995 BMW 525i seems to be “shuddering” or stutter shifting slightly when shifting from 2nd to 3rd and again when shifting from 3rd to 4th when warm. Shifting seems fine with the engine cold.
Transmission was last serviced (drain and fill) 18,000 miles ago with Valvoline Dexron VI and new filter. Car now has 198,000 miles with original transmission.
I have heard the tranmission control module and/or solenoids can cause shift issues and the transmission is not failing. Also heard a bad center bearing or driveshaft problem can cause a shudder when shifting.
Any thoughts on what may be the issue?
