I Have A 94 F 150 The Problem I Have Is The Tag On The Door Jam Says Its A Type U Trans Which Is A C6 Trans But Its Not Ithink Its A Aod Trans.... It Has 14 Bolts In The Pan I Need To Know If Im Wright Or Wrong The Real Problem Im Having Is It Drops Out Of Overdrive The Off Light On The Gearstick Is Flashing Any Help Woulb Be Helpful Thank U

 

CAN ANYONE HELP ME

 

Here are some transmission pan diagrams. Also the C6 is a 3 speed and the AOD is a 4 speed. If you have the OD button on the Gear Shift then I'd guess its an AOD-E / 4R70W.

 

ITS THE AOD PATTERN WHAT WOULD BECAUSING IT TO DOWN SHIFT

 

I dunno, you need to get a code scanner or take it to a major auto parts store (i.e. Autozone, Advance Auto, etc.) and get them to run a code scan to see if your truck is throwing any trouble codes. Thats where I would start.

 

THE CHECK LIGHT ISNT ON CAN THEY STILL CHECK ITS A 94 THANKS FOR THE HELP

 

Hmmm, yea they can still check it. I would think that if the OD light is flashing then some type of trouble code would be recorded in the computer. Maybe try doing a search on GOOGLE about it. Sorry I can't help you anymore then that bud. Its hard to troubleshoot over the internet, haha.

 

The check engine light doesn't have to be on for there to be codes in there. You don't need a scanner to check the codes on that, you can use a paper clip or piece of wire.

 

I knew about that trick on my old Mustang but didn't know that it would work on his truck. Yea isn't it something like a "Hard" code will sit off the CEL, but a "Soft" code will just be stored.

--Ok just found this by doing a GOOGLE search.

Hope it helps some

 

Something like that. KOEO codes are detected at the time of the test, continuous codes are failures which occured over the last 40-80 driving cycles. Then there is an engine running test to detect faults while running.
