Tranny...what would you do?

[ryaleon]

So my 3-4 clutch pack is out two shops in my are have quoted between $2500 and 3000 for an overhaul.

Should I try and find a rebuilt tranny or one that was removed from a wrecked H2 and just swap trannys....or should I pay the rebuild cost?

I am mechanically inclined but am not sure what all goes into swapping a tranny. Really doesn't seem too hard but I am not sure. Is it something I could do myself?

You can buy a new transmission from GMPartsOutlet for less than $1,700 and shouldn't cost more than $300 to have it swapped out by a good mechanic. I wouldn't tackle any transmission swap because you will need special tools and lift system.

That sounds high! AAMCO quoted me a rebuild price of $1650 on my 2004 H2 transmission in 2009 before I bought my current SUT. I went with it and was very happy with the rebuilt transmission. I don't think prices have gone up that much since 2009.

I paid $2250 last November for a rebuilt one with unlimited mileage. I had 133xxx miles.
The shop said is was a real SOB to put the new one in, plus the H2 computer needed to be hooked up to some machine to 'accept' the new tranny / codes, etc.

Yeah I was worried I'd run into issues midway the swap and then be screwed. So I def will not do the install myself then. Guess I'll just have to hunt for a cheap tranny shop that does good work.

What do you guys think about getting this tranny?

One day I'd like to do the 4L80E swap

I'd caution about AAMCO, I've had one rebuilt there and it did not shift right when cold, and I could not get them to look into it, and not long ago I was with a guy who pulled a AAMCO rebuilt tranny apart because they wouldnt look at it again after he had had some problems, he found parts marked with the name of a local junkyard..

My 10 cents on AAMCO

Here's a smoking deal on the 4L80E

Finally had some time to take h2 to a different shop. Quoted $1100-1800 for rebuild with HD components and new tc.

about 4 months ago i blew my tranny up in nebraska, the tranny alone cost $2900 iirc and total after labor, and a few other things i spent about $5k

my tranny is still doing great. the shop called about 2 weeks after i picked it up to report that i needed a external cooler or to swap my radiator due to trace amount of coolant detected in my old tranny. i installed a external shortly afterwards.

the trans shifts lift a mofo from 1 to 2 gear, and still a noticable shift from 2 to 3.

anyone who rides in it says it is not normal to shift so hard.

i admit i was in a hard spot when my tranny blew, and didnt have alot of time or choices.
the transmission is a roadripper 2000
comes with a 30k warranty

my new concern now is that my diffs/TC cant handle the shifts from the new tranny and are my new weak point in the drivetrain
with 4.88 gears & 37 inch tires.. i admit it is a beast when i stomp the gas from a dead stop.. i have heard my tires chirp(sometimes) when it shifts.. which i wouldnt think is impossible.

while i know im not a racer, it is a damn good feeling when i can best cars off the line. granted 1-2 shift is very short, but when it hits 2nd, OMG the the range is huge before it shifts 2-3... :) i admit, it will make your cock hard sometimes when you stomp it!

the actual tranny swap isnt difficult really.
the only special tool you will really need is a alignment tool.

the big thing is you might not be able to drive it until your ECM is flashed to accept it.

im not promoting the roadripper.... i can only speak from my exp.

honestly, $1800 is respectable.. and for the TC? is that transfer case rebuild/replacement?

if so, do it!

for that price, not only would i do it, i would go extra and insist on not HD, but extreme HD parts for both.

otherwise find a 4E80L and have it rebuilt and installed.

[ryaleon]

Oh by tc i meant torque converter. I'm pretty excited to be able to take my hummer out on the highway again.

Getting the H2 back tomorrow afternoon. Feel like a kid on xmas eve right now.
