prerunner truck transmission

[dezerts10]

what are truckas like the "luxury/ TT prerunners" using for there transmissions?

I have a mixed feelings about going t400 in my truck cause its only a 3 speed and my plans are to build it then trailer it to baja and drive it everywhere so that means long drives on the highway with a 3 speed thats annoying and reved out as well. I was looking at trememc t 56 transmissions too and they are 6 speeds transmissions which would be good for my needs. 1 2 3 4 inthe dirt 5 and 6 for the long cruising ont he high ways.

is there anythign i could do to a t400 to make it crusie better onthe highway? should i look at a different trans? i dont want anything that requires a computer to operate that is a key factor.

hmm might have to drive over on the way to work and ask tony about this.

How 'bout a gear vendor type overdrive unit?

[FullsizeFun]

4L80E is the way to go. My truck runs 37's with 4.88 gears and cruises on the highway @ 75-80mph no problem

You can put an overdrive in a TH400 or build a 4L80E (I think thats correct). I have been told the gear options on the 4L80E are not great for offroad and you have to run more gear in the rear but they are doable. The black newer F150 prerunner of Nick Baldwins that was finished last year has a 4L80E in it. Culhane can help you out and has a lot of good information.

My choices would be in the following order:

4L80E
Viperized T-56
T400 w/ gear vender

The T-56 is only second because I like an slushbox in the desert better (I normally prefer manuals in everything else).

[Cerberus2k7]

Only real issue is weight. The 80e is around 260lbs wet IIRC.

nd looking at the trans and the price onthe clutch that is what got me thinking of something else.

[zblink]

looked into a 4l80 for my f150 that i am planning on building and buying a built one wasn't exactly cheap

[philofab]

What motor are you running it behind?

[dirtdudeaz]

finish line transmissions builds these things up pretty good from what I hear. And if you have a gm tranny already you send in your housing and they send you a built one and it is a lot cheaper.

Gear it so its a 2nd gear cruiser... Its a prerunner it doesnt have to be a rocket ship. I'd take reliability over speed any day. I'd say t400.

You just need to spend more time in something faster :)

What motor are you running it behind?

4.3L v6. basically a steel cab with a/c 7200 truck but i prolly wont run glass and im just gonna panel it in truggy style

What are you looking at power wise? 80e might not be ideal. They rob a good bit of power as well.

X2... a 4L65 or 200r4 may be better. 4L80E and T400 rob a lot of power.

[dezerts10]

it needs to 100% manual. I do not want to run a stand alone computer system for the trans. I told the engine builder 300 to 350 hp as reliable as possible is what I wanted said its should be doable easily so thats what im looking for

Weight/power is still a bit of an issue, but we ran a LQ9/4l80e non-electronic from Transmission Center with a ratchet shifter in the drag car.

A Lenco would rock....

[1450Toyota]

I actually stopped by Lenco 2 weeks ago....I live right down the street...They are putting a LencoDrive trans in a TT...not cheap...12,000 for a 3 speed....But they have Great Trans and Great Customer Service! :D

[fas_guy]

sounds like the 4l80e is the way to go, I want a strong trannie with o/d but I've heard the aod is weak even if you build it that they just can't handle more than 300 hp. Sounds like I need to find a way to put the 4l80 behind my 351w any suggestions? :confused:

4l85e

[fas_guy]

4l85e

Difference between 4L80e & 4L85e ? didn't even know there was an 85 what do they come in?

Not much. It's just a factory upgraded 4L80. Same case, just a few better parts here and there.

[Mcarlson1]

4l80 and 85 is gonna be to much for the 4.3, id use a 4l60/65e for the v6, they use em in 96-current small blocks in gms and are pretty reliable, and if your gonna be running 300-350 hp itll be perfect for it. Just my 2 cents.

Thanks,
Mike
