I recently purchased a well cared for 93 turbo wagon.(I have a whole box of records from the original owner) The Motor seems very strong. The tranny also seems very strong, as it shifts well. It has had a tranny put in it though.
The issue I'm having is during slow right hand turns, mostly tight, I get a surging or binding in the car. It's super faint, but it's noticeable. Like it grabs, let's go, grabs etc. It does not chirp the tires or buck on u - turns. It also doesn't do anything weird when I shut it off. No lights on the dash. Just the power light for a second when I start the car.
I'm guessing something is starting to go bad. I changed the fluid recently. Seemed to somewhat help.
Could this be a duty c issue? Do 4eats have a viscous unit?
