I have some tranny issues on my 1991 Ls 400 when I start the car Its as if the fly wheel is grinding. It seems to ingage normal when going from stand still to acceleration, however after it goes past 4k rpm it gets sluggish. The OD light flashes when its on. When I turn off the OD its normal.

Any write ups on changing the Tranny filter and fluid? Cause that is what Im gonna do first.


Thanks

Here is a step by step with pic walk thru for changing tranny oil and filter.

Pretty easy stuff... I would say try to get the trouble code from the tranny and see what it says. Might be a bad solenoid.

 

Thanks man good looking out!!
