The whomp did pull the cable, whis is why I did it. Because the motor DID NOT rev, I don’t think pressures changed to cause the shift to 4th. THAT’S why I’m thinking sticky valve or too much preload in the cable.

The real issue, I guess, is why the trans started acting differently. I did not mess with the cable when I did the fluid and filter change. The trans worked as before for 1500 miles after that. It woukd stand to reason that cable and geometry are not at fault, but rather, as suggeted, something internal, not related to the cable or fluid. A stick valve would seem to fit that bill...Anyone agree or not?

How much would it cost you to get a transmission shop to just adj the TV cable with a pressure guage? Seems to be a 20 min job. If you got the TV cable adj exactly right, at least that would either fix it or be out of the picture.

Go 55 and move your shifter from OD to D, D to OD and go back and fourth... see if it shifts. Do it 5 to 10 times.

Also, I read one of your posts saying you put Lucas in with your trans already full but then lost so fluid. Got to make sure your dead on full mark on dipstick after you drive 11 miles to work.

I moved the brass thingy just a tad to add a touch more tension because it was shifting entirely too soon. Now it shifts at (GPS) 20, 30, and 45 under very light throttle.

Awesome! I believe that is exactly how it should shift according to the sites and videos ive seen. I'd say you fixed it and im glad you didnt drop the pan and monkey around with stuff that wasnt broke. Good deal!

Thanks. Still weird, tho.

Well crap. Reverse quit. Just when it was working as it should...

Any noises other than the wallet coming out of your back pocket.

nope. Just wouldn't go one day. Forward gears are all fine. the jaw drop was louder than the wallet...

You still driving it and when you park make sure you don’t have to use reverse.

Well you did get to use it for a few months after the transmission got new fluid. Do you think you may drop the pan and see the burnt up clutch material in the pan

Do you think a valve is stuck. Fluid look great.

The tv cable adjustment can not fix a no reverse issue.

Haven’t dropped the pan yet. Sacred to. Will drive it to a shop. Will report back.

Hope it all works out for you and the FOX. Best of Luck.

Thanks. We'll see.
