is there a diffrence in the cross member for a manual tranny and a automatic tranny. doing my upgrade and mine has a manual tranny and im putting in a E4OD tranny in it. if there is a diffrence can i use the automatic crossmember with little modification. been told its the same length as C-6 but havnt confirmed this.

 

It's not officially called a crossmember, it's called the rear engine mount (or transmission mount) bracket.

The 1965/72 F100/250 352/360/390 2WD bracket is the same with an A/T (MX Cruise-O & C6).

It is not the same bracket as a M/T uses, it is not the same bracket for 4WD's or F350's.

1965/67 F100/250 352 w/MX Cruise-O-Matic & 1968/72 F100/250 360/390 2WD w/a C6 > >

Ford part number: C8TZ-6A023-A .. Bracket

However, I do not know if this bracket will work with an E4OD, which wasn't introduced in F150's till the mid 1990's (1989 on F250/350's).

I had a 79 F-100 years ago that some one had a 351w and an (EAOD), It did
have the stock trans crossmember, seems like they had to drill new holes in the frame, I think it sat further bad!


P.S. when I got the 79 it needed an oil pump, I replaced the oil pump on the
351w without pulling the motor, then drove it some, pulled motor and trans
sold the truck, sold the trans, installed the 78 351w in a 70 GALAXIE, removed
the 69 351w from the car, and traded the car for a 69 F-100.

i did some reading and found out the e4od is three inches longer. so if i use the same transmission crossmember with a c-6 mount, i think ill only have to slide it back 3 inches and drill some holes. im going to the junk yard this week so ill grab a couple mounts from diffrent years and see what works. numberdummy you make are lifes some much easier, thanks

 

My AODE/4R70W bolted to the factory crossmember and used the same mount as my 3 speed did that I had in there years ago, in fact I have not changed the mount it is the same one that has been on the truck for over 40 years. I can not speak if the E4OD takes the same mount, but you might get lucky. I left my transmission cross member in the same set of holes, but I made new motor mounts and could locate it where ever I wanted, I chose to leave it as the oil pan for the transmission can be serviced with no problem, if I moved the cross member forward the pan would hit the cross member right below the engine fly wheel. This is the cross member that is pop riveted in place and your radious arms mount there as well. It might not have been right, or called out in a book but my rear engine mount/transmission mount is the same piece that came with my truck brand new. To date I have had the factory 3 on the tree, T-18 and NP-435 4 speed, C-4, C-6 and now my 4R70W and used the same mount.

Since you are using a 5.8L my guess is you will be using the engine perches you have now and therefor might have to move your transmission mount back, but like you said just drill 4 new holes in the frame to bolt it down. I have drilled several holes in my frame to mount things and it drills pretty easy with a good set of drill bits.

Sorry to change the subject, but did you figure your wiring out? I sent you a second email but I do not know if you got it, when I replied to you on your second email it kicked it back to me, so I copied and pasted to your first email and sent it again.
