I have a 6.5td with a 4l80e and I am wondering where I am suppose to connect the signal wires from the tach to. I find in manuals and many google searches for the oil pump driven ones for 6.2 and 6.5na and that sensor can't be used since the turbo is in the way. Much thanks to anyone who can...

I have a 4L80E and it needs the crank shaft speed sensor for RPM. However the 6.5 should have a hole in the timing cover for it.

Hopefully this helps.

I am from CO and I have driven in 3ft of snow and more reasonable amounts for years and it does just fine. We don't have a ton of ice on the streets usually as probably your part does so it might vary in that aspect. If it is a bit slick on the road, the H/L will usually take care of that (or it...

I put a 6.5td and 4l80e in mine and although it is time consuming, it is very much worth it in my eyes. The extra power and the overdrive are great. I kept it factory correct as well and have had no problems.

No HMMWVs have intercoolers but there is a kit out there to put one on. I only had to change the drives shafts so they fit the 4L80E to transfer case (which I have the NP242) and the output from the transfer case. Since yours already has those components I don't see any reason why the drive...

I know what they're saying because they're referring to the ECV HMMWV which is an A2 with beefed up cooling and new body style, but I have an A0 with the old body style and certainly isn't an ECV and it took the 6.5td easily. The harness was the only major thing I had to change. Just to help put...

If they come with the 4L80E, then I would think they would have the harness to accompany it. It would be a bit rediculous if they took it out but you never know. The engines are interchangeable fairly easily. With my 6.5td, It went in easily and just barely fit under the body (just below the...

Side mounted won't fit between the frame. It has to be rear mounted. Also have to get the A2 doghouse to fit over the rear turbo.

It has to have a rear mounted turbo to fit in the HMMWV. I can't tell you what all vehicles have that. Also if it's not set up for military you would have to make to get 24v items for it unless your HMMWV is 12v.

I upgraded my from the 6.2 with 3L80 to a 6.5TD with 4L80E. The is a considerable difference in power between those two. I do live quite high up (about 8000ft) and the turbo is much needed at that altitude. Some people have turbo charged the 6.2 but that's up to you. There wasn't a wiring...

Thank you for your help.

I took the 3L80 out of my HMMWV to put the 4L80E in and am now looking to sell the 3L80 (not promoting any selling right now). The transmission has 30,000 miles on it, is in good condition, worked great just wanted the extra gear, and I am wondering what you all think would be a good asking...

I have seen this before and it is one of the two problems you already identified.

It would be interesting to see the actual weight difference. Where do you even find these 24 bolt rims?
