I have a 86 F150 5.0 EFI. AOD Trans. 2 problems have started at the same time. The trans doesnt shift correct. It wont shift out of 1st until I hit about 20 to 30 unless I let off the gas and shifts late in the rest of the gears it also down shifts to easly. Next prob. It running a little ruff at a idle but not to bad but when I try to hit the gas it just feels like the motor is being held back runs ruff just no power and the hole truck kinda shakes. Now for the very long list of parts I have already replaced. Idle air control sensor, knock sensor, pick up coil, control module, wires, plugs, cap, rotor, air charge temp sensor, thermo temp sensor, Now the cat was also stopped up I think so I just ran a peice of rebar thru it for a test. HELP

That is a very good possibility.Cheaper than a tranny too.Sorry I didn't mention that at least.It should be a speed sensor or something that tells what the RPMs are for shifting so it doesn't wind out.No metal is a great indicator too.Sorry about that.If you decide I wasn't enough help or did not solve it properly no hard feelings.I am not in it to make as much money as possible.I answer at least 10x more freebies than $ ones.Good luck!
