Do I have a C-6?

What do I look for to see if I have a c-6 tranny. I have a 1990 f-150 4X4 supercab shortbed. Just bought it today so any info would be great. Looking forward on talking with you people while I build up this truck.

I doubt it probably an E4OD

There's a tranny code on the door pillar. Does the shifter have an OD position, or an OD on/off button on the dash or shifter stalk?

A quick way to identify it is using the tranny pan bolt pattern.

It does have an overdrive button on the dash. Is the E40D a good tranny.

A button on the dash is the AODE(4R70w) potentially.. what does the tranny oilpan look like?

Paul,

I thought the E4OD was the only tranny with a push button overdrive. An AODE should have a P-R-N-(D)-D-1 shift pattern.

Maybe I'm wrong...good change to learn me something!

I'm not a 100% certain either, I test drove a '90 5.8 powered truck when I was shopping a few years ago and it had the OD button on the dash, I seem to remember reading that was the AODE tranny...but I could be mistaken.

My 90 had the OD button on the dash as well, I always just assumed that it was an
E4OD because the AODs I was aware of were forced in and out of OD by the shift linkage.

Stupid me, I never wrote down what was on that door tag, now I've got myself wondering. It was a very different animal than the non-electronic AOD in my newer truck.

I am 99% sure that I have the E40D tranny. The pan doesnt look anything like any of the ones below, but I found the owners manual and I went by that. Is there a website that has complete specs? I have so many questions and I dont want to bug you guys for stuff I could look up myself
