6 speed?

[InternationalHarvester7.3]

Alright I got a 96 7.3 with a 5 speed manual transmission, I want to know if I can swap a 6 speed from the newer 7.3 models and what the benefits would be?

U can but its not a direct swap. U will need to custom make a trans cross member, add a trans cooler and lines, swap the t-case, shorten rear d-shaft, lengthen front d-shaft.

No real benefit then a slightly higher 6th and a lower 1st with less span in between each gear. Just leave your 5 speed in!

Don't let others stop you, if I had a truck with stick I would do it

I had a semi on topic question about this do you guys think it would be worth swapping in a zf5 for the e40d. What would it entail to to do it and what benefits could I see. Goal for the truck is approxamently 550-600hp

So your getting rid of auto and going manual? Pretty much same stuff, drive shafts are different lengths, not sure about cross members tho, and you will need PCM to be tuned not to throw transmission codes

[doyle95]

So not worth it?

Just depends on if you want stick or just have your auto built to hold up to that kind of power

[doyle95]

Well I love driving stick but what would be the price difference do you think
