I have an 88 XJ with 306k on the tranny. It is the auto 4spd, I think the AW4, but can't remember right now.
It use to run at ~1800 rpm at 60 mph, and when in OD, it would slowly accelerate if you gave it just a little gas.
Now, it runs 2000-2200 rpm at 55 mph, and when you give it a little gas, the rpm jumps 300 or so rpm.
It acts to me like it is not going into lockup or OD fully, and sometimes it does, and sometimes it doesn't. the engine sound is defintely higher now crusing doen the road.
What can I check before I get a new tranny ??
The fluid level is fine, and fluid looks/smells normal.
