looking at a 96 f250 with a 7.3 powerstroke, it has a automatic, that shifts only when you let off gas, do you know what transmission it is? 4r100? and any idea why it shifts like that?

 

It probably has an E4OD. Does it have OD OFF on the end of the shifter? If so, that's the E4OD. If not, it has a C6.

 

I also have the E40D in my 450. What is the average life of the E40D? I had mine rebuilt at 40,000 and it now has 138,000. Was wondering if I should do a rebuild again. Once in a while it shifts hard but other than that it seems fine. Most of the time it is pulling a trailer or body is loaded with materials. I change the fluid and filter every winter which is about 8,000 miles per year.

 

Should be an E4OD in that 96, just went thru the rebuild thing, what a pain!! Finally got it right so I'm very happy!! As for life expectancy figure 100k miles normal driving, but ymmv..

 

It could be a C6. Both were available in 1996.

The E4OD can last over 200,000 miles. I've seen them do that. Changing the fluid often helps.

 

I may be wrong what tranny I have. I have a 95 450. Did they have the C6 and the E40D in 95?

 

Yes they did. Both the C6 and E4OD were available from 1989 through 1996. You could have either.

 

I have almost 270k on my e4od... It still works but the 2-3 shift is a bit sloppy now

 

Is there a easy way of identifying what tranny is in it? Maybe a code in the vin or they look diferent. Is one more durable than the other?

 

if you have the OD button on the end of the shifter it is an e4od

I do have the OD button on the shifter so I have the E40D. Thanks Guys for the info.

 

well if its a c6 i would be thrilled

 

I wouldn't, but everyone has their favorites. I'd much rather have an E4OD than a C6.

Which one do you have?

 

I believe the E40D is based on the C6... they just added an extra gear.

You're right. The E4OD is basically a C6 with an overdrive, a lockup torque converter, and electronics.
