HELP!!!!
I will try to be brief but somehow I know there will not be short answer...lol
I recently swapped a 4.0 explorer into a 91 bronco II for a customer ( I don't have a fancy shop just like working on fords for good folks). He gave up on the old 2.9 and found a 75k mile 4.0 with all the harnesses entirely except for the dash wiring. I did my homework and found a wiring diagram on this forum that pointed out all the wiring on the drivers fender. long story short the engine runs beautifully. all systems go except one! I get a cel light and the bronco wont shift out of 1st gear. if I manualy select 2nd it will go there and I can run it out to about 50mph in second and the cel light will go out briefly throughout the rpm range which leads me to believe the cel is transmission related.
I went over my wiring tonight for the second time and cannot find missing wires.
this is the original transmission from the 2.9 I should add. and as far as I know it ran fine when the customer brought it to me.
why cant we just have it simple like the old c-4 trannys that shifted on vacuum? im hoping one of you tranny gurus can point me in the right direction on what it sounds like.
I used the 4.0 computer and relays along with the 4.0 engine harness. I retained the bronco headlight harness so I had to merge the two on drivers side fender as stated. I have all functions as normal. except for the shifting.
thanks for any help.
