Ford experts/Transmission experts/Experts in general(ANYONE)
It is with a heavy heart and a wounded pride that I have come here today. I have a problem and I quite simply can NOT figure it out. I only have two options on this. I will present the options, and then the problem.
#1: Keep plugging and hopefully figure out the problem and fix it.
#2: Tow the car to ohio(some 500 miles?) and have the guy who built the transmission make it work.
Here is the brain buster.
I have a 1995 Ford Thunderbrd LX 4.6L with a 2000+ 4R70W transmission out of a Crown Victoria. This transmission has the 8 tooth output shaft vs. the 7 tooth that my car came with.
The TC is a 2004 Mercury Marauder that has been rebuilt.
It has a modified valve body and different springs(shift kit).
I have repinned the harness to accept the transmission wiring pins and all should be well on that front.
I have rewired the entire EEC(computer), installed a speedcal, tried two output shaft sensors and two vehicle speed sensors.
I have a custom chip burned for the setup I have. The trans/gears/etc.
The issue is that when in D, it will shift 1/2 and 2/3 AND 3/4 all before 20 MPH and then fully apply the TCC.
So with that information given, I am asking... no... begging for someone to shed some light on this situation. I don't like asking for help, and I know this is a GM specific forum. I'm not starting this thread to hear any of the usual B.*. about how I should just get a GM. I just want honest to (insert religious/spiritual figure here) facts.
