Forgot to mention that. Is there a recommended adjustment and what does it prevent ?



Thanks. .

Thanks SW. Also been looking for a photo/schematic for this trans and so far haven't found one. Do you know of one ?

As for the rear adj. I had just replaced the fluid and in the inspection process noticed an adjustment arm w/a lock nut. Movement up and down was quite a bit. Is that the adjustment point ? Looks like the arm is connected to a valve of sorts.
