Hey everyone here we go again with more problems, this time it's my girl friends truck... just had the transmission rebuilt after the original stopped working all together... the truck is a 1993 f350 4x4 crew cab long bed srw 6.9 idi (serp-belt swapped, injection pump turned up a little ) with a e4od.
Now the owner before us sold the truck stating it had a bad transmission... it slipped and would lose the torque converter randomly until one day it was all done and wouldn't move anymore.. so I pulled the transmission myself, realized after ordering everything I was over my head in a automatic rebuild, and brought it to a transmission shop.. where they told me it would be 300 in labor, I agreed and left it expecting to get a torque converter later after researching about what kind would best fit the budget.. well the shop called my girl friend and she oked them putting a dayco (however it's spelt) TC and a Trans go shift kit. They also informed her that there was a bad solenoid. Now the bill is 700, not counting the Trans star rebuild kit 350...
regardless I get the Trans back install it and it shifted great, until it warmed up.. now it slams gears, the torque converter locks in reverse and 1st all the time and randomly in D. I had no over drive what so ever for the ride from my shop to the Trans shop, we also lost 3rd gear for a little bit.. Trans shop in short said not our problem well look at it whenever we get to it so after a week I went and grabbed the truck. I had forgotten the guy who previously owned it had attempted the torque converter lock up switch mod, so I rewired it in and I had overdrive and a locking torque converter only when the switch was engaged. I then git the truck home and removed the wiring and switch and the truck is back to stock. I also took the Trans pan down to see if the filter was sucking air from the top (if it fell down or had the wrong filter) then I reset the throttle position sensor to 1.2 volts, and 1.2 volts neither make a difference.. cleaned all connections to the transmission and cleaned the speed sensor, then replaced the throttle position with a known working one off of my 7.3 idi
The only progress I've made is I now have 1 2 3 and over drive slamming gears... it still stalls in reverse and 1... and some times in D. I don't know much about automatics so please tel me what I an missing.. the only other thing I forgot to mention is that the tcm ( the black box where the shifting linkage goes I assume ) is also new.
Any input is greatly appreciated
