No previous problems. No leaks went to drive it and nothing but reverse. I jacked it up level, took the full plug out and a small amount of fluid came out and it appears to be full
My suggestion to is to drop the filter and valve body and then clean the valve body passages, the solenoids and install a new filter with fresh fluid.
Otherwise you will need to pull the transmission to repair it.
Don't forget to do a scan with a diagnostic tool and check if you have any error in your transmission.
Sorry maybe I didn't get your right.... you have problem with Revers Gear right ??? Can you give me symptoms ?
I only have reverse on a automatic transmission
I had driven it the day before,about ten days ago and I started it up warmed it up to operating temperature and got no forward gears.
