Well.
I'm trying my hardest to get my v8 powered B3000 shortbox project on the road. I've done most of the work myself including the install of a freshly rebuilt 289 out of a 65 Mustang and a used AOD transmission out of a 93 Mustang.
I didn't bother rebuilding the tranny as I was told that it was working fine when pulled but went ahead and changed the filter and topped up the fluid including the torque convertor. The fluid in the pan was not exactly clean but did not appear or smell burnt and there were no bits of clutch material that I could see.
After watching several online videos about the correct way to set the TV cable I thought I had it right and took it for a test drive. Results were lazy shift between 1/2 and absolutely no 3/4 shifts. Took it back to garage and put a 100 psi gauge into the TV test port on passenger side as described.
Apparantly the idle pressure supposed to be 0-5 psi raising to around 25 psi with the 5/16" spacer gauge installed.
Well. I couldn't get the pressure below 16 psi no matter what I did. The engine was idling around 900 rpm. I tried pushing the lever back with my fingers but it was already at the zero position.
At approx 4000 rpm the gauge showed close to 75 psi with a gradual rise (not jerky) at the rpms in between.
I played around with the ratio between carb/throttle lever and TV lever movement and although I was able to get 1st and second feeling right, there was still no shift or attempted shift to third gear.
I verified the newly installed B&M shifter and cable were selecting the "D" detent on the transmission properly
Does anybody know what the problem might be ? I'm wondering if it might not be a dirty VB or stuck 3/4 servo ?
Maybe I should've just bypassed the AOD and went with a C4 but I was looking for something that could give me some decent fuel mileage when I was out on the highway
