New guy, some questions

[02greysixer]

Alright guys, I'm looking at my first powerstroke. I'm a Duramax guy so don't flame me! The truck I'm looking at is a 94 F350 regular cab 5 speed with a flatbed. question one is, I'd like to convert the truck from 5 speed to an automatic. What's the best way to do that? Will a C-6 bolt up? And will a 1/2 ton lwb bed fit on the frame or do I need to find an F350 bed for it?

Not looking for perfection, and I don't need overdrive because the truck is going up on 2.5 ton axles and 50ish inch tractor tires. Thanks in advance!

im sure you can find a person around you that will trade you a 5 speed foran automatic. i belive the c-6 bolt pattern is different so i think you are stuck with an e4od or a r4100

You can use a C6 from behind a Idi diesel will also need the flex plate. your transfer case will bolt up but will need different driveshafts since the C6 is shorter than the E4od or Zf 5 speed. 1/2 - 3/4 ton bed will fit as long as it's not a cab and chassis.

Ok so a C-6 from an IDI will fit, great! What year truck would I need to look for to get it from? And driveshafts aren't an issue since they will need to be custom made anyway. And how do I tell if it is a cab and chassis truck? And what needs to be done to put a bed on a cc if it is? Cut the frame down and make mounts?

Thanks for the replies!

personally if you're looking for a regular cab with an auto an a tranny I'd get just that. It'd be a lot easier than going manual to auto. Automatics with a bed are not hard to find for a decent price

IDI 7.3's were 87-early 94. I don't know what years had the C6, probably 87-91 would be my guess. CC should all be dually's... You should be fine as long as it's not a dually.

But I'd have to say you're probably better of finding an auto reg cab truck, they seem to be pretty common. But If you want a project, nothing like a tranny swap!

The C6 was behind the 6.9 idi also so check from 83-89, I believe 89 was first year of E4od but don't know if the C6 was still used

[Frozen Redneck]

I didn't know the 6.9 C6 would bolt up? Sweet!

i believe the c6 was used up until 94, but i'm not sure if it was used behind the IDI till then (you could get in behind a 460) the 460 have a different bellhousing. and yes there are guys out there wanting the do 5 speed swaps. where are you I have a truck i would love to put a 5 speed in?
