I want to thank you so much for clarifying on how to do this swap without having to get new driveshafts made I have the exact project sitting on ice for 5 years. I actually ended up getting a np241c made up as well but now I’m stuck on the speedometer on a budget. Now I’ll go check if my dirty dingos have that offset.

No problem, get that thing finished up and drive it!

2wd or earlier 4L80E core. = rear speed sensor = keep cable for stock speedo

Wow, nice . That sensor helped you out alot. Im going to use the Dakota Digital's speedo/tach converter so my original Crown Vic speedo will work. Gm trans with a Ford speedo lol.

Yeah it's really convenient. The speedo tach converters aren't bad either though!

Great video man! Thank you so much for this info. Where or what website did you get the mount for the 4l80e to np208 adapter? Thats the last piece I need for my swap! Thanks again!
@MohawkMotors2 ай бұрын
Thank you! Glad it helped! The NP208 has the same bolt pattern as the more modern transfer cases, readily available in junkyards, on amazon, rock auto, autozone, napa, etc. Just an adapter for a 2000 to 2006 4x4 2500HD with a gas engine.

If I use a 2wd 4L80E and cut the tail housing shaft will I need to run a VSS on the t-case or will the 2wd 4L80E already have a VSS running to the computer
@MohawkMotorsАй бұрын
A 2wd 4l80e should already have an output speed sensor on it.

So if I buy a 2wd 4l80e, cut the shaft, and get the adapters then I don't need vss on the np208 transfer case? 4x4 still works correctly? Thanks!
@MohawkMotorsАй бұрын
Yes that would work, and you wouldn't need a vss on the transfer case.

Hey there glad I came across your videos. so I’m doing the same swap. 87 k10 6.0 4l80e 2wd with the 208 32 spline swap. My question is. I plugged off the rear 2wd tail cone hole for the rear seal. But noticed a drain hole on the bottom of the back of the trans. do I need too plug that hole? So fluid don’t come back into the trans / t case adapter ?? So far I haven’t seen anyone mention anything about that what I believe is a drain hole.
@MohawkMotors10 ай бұрын
The small drain hole at the bottom rear of the transmission case you leave open, it allows the space in the adapter to "breathe" and if any transmission fluid get's past the rear seal of the transmission it will be able to drain back into the pan.

Awesome thanks for you reply back. I appreciate it. Do you remember what flex plate you used? Part number? Or just any info you have on it.

Great video, thanks for the info. I have an 84’ K20 and want to do this, but with original 350. I know that certain years and old vans have a controller for trans, but What I read, the 2wd output is different from 4wd, so a 2wd 4l80 won’t work in a 4wd? If you can shed any light on my confusion, I’d appreciate it.
@MohawkMotors5 ай бұрын
you've read correctly, the earlier models, I believe up to 1995 had a separate transmission controller. Yes the 2wd and 4wd transmissions have different output shafts. There are actually 3 lengths of output shaft, the 4wd output, the 2wd with a fixed yoke output, and the 2wd with a slip yoke output. Technically you can make any of them work in a 4wd application since the 4wd output is the shortest, you can just cut the 2wd outputs shorter to work in a 4wd application.
@Dano5004 ай бұрын
@@MohawkMotors You are awesome! Thank you. I don't suppose I could push it and ask how much I would have to cut off between both the fixed and slip yoke?
@pingeralert54965 ай бұрын
So just to clarify you used a 2wd 4l80e. But did not change the tail shaft to a 4wd output shaft? the 2wd spline on the trans fits right in the transfer just with the adapter?
@MohawkMotors5 ай бұрын
No, sorry if I wasn't clear, the transmission was set up as a 4wd transmission, it has the 4wd output shaft, BUT whoever rebuilt the transmission used an output carrier assembly from a 2wd transmission. The only difference between the 2wd output carrier assembly and the 4wd output carrier assembly is the 2wd output carrier assembly has the toothed ring on the outside for an output speed sensor. They are interchangeable.

Do you have a link or part number for the crossmember bushing?

You mean the transmission mount? Standard transmission mount for 99 to 06 4x4 silverado or sierra

Hm, I don't have a range shift indicator on my 4l80e for this swap...Is that necessary?
@MohawkMotors10 ай бұрын
Only things you need the range indicator on the side for is neutral safety if you want to have it, and reverse lights.
@1bad69xss410 ай бұрын
1/4" is a lil much. Typical ideal gap is 1/8"-3/16".
@MohawkMotors10 ай бұрын
yup, just used some 1/8th spacers and that got it right where I wanted it when all tightened together.

Will that adapter work on a np205?
@MohawkMotors7 ай бұрын
It won't fit an NP205 without modification. You would need to modify/clearance the adapter to clear the upper shift rail of the NP205. You would also want to add some other form of support for the transfer case due to the NP205 being substantially heavier than the aluminum chain driven transfer cases.
