    Is it possible to install a 4l80 transmission in my 07 H-3 with the 3.7 engine?

    A 4L60E can be built for 1,000 HP and has in drag applications, that is significantly more than a mild LS motor. It is all a matter of how much do you want to spend to abuse it. ;) The best way is to sell your I5 and buy an Alpha, then mod that.

    H3 Motor mounts for 2008 Alpha

    They made a bunch of 09 -12 5.3L Collys and Canyons. Many of those owners are customers. The 2WD versions with some tweeks can haul azz, like this customer at Milan Dragway! Just sayin......... Back to your regular H4O programming. And, No. Just because it is a GM truck don't mean parts...

    H3 won't hold a charge (AC)

    FYI when H3s were built, GM put refrigerant dye in the system. All GMs made since 2005/06 have it from the factory. The only time you need to add dye is when you do a flush and vac of the system.

    Rear end.

    I would start out by posting my question in the H3 section where all H3 tech questions belong. I assume a Mod will come along and MOVE this for you. Answer to your question: 1) get it rebuilt at your local ring and pinion/differential service facility if you cannot do it yourself; or, 2) get a...

    Missing Fuses 10 and 11

    They are using your fuse block, and have independent fuse protection for the tapped circuit and the added circuit. He is adding LED lights that typically have low demands. Better than a used no longer available plug IMHO. He was asking for a solution, I offered one. There are many ways to...

    what rear shocks are you guys running?

    Seen too many Bilstein shocks leak to bother with those. Used to put them on Steel Bumper Vettes (different animals) and they were great. For trucks today, not so much. Rancho used to make great shocks for trucks 20-25 years ago, .............. now, not so much. Not what they where then...

    No reverse

    2006s do not have a TCM, those were used 2008+. 2006 & 7s control the AT with the PCM. Common failure of the 4L60E is ===== No Reverse. Usually some slipping in any forward gear along with that or right after.

    H3 Alpha mods.

    I have not 100% dialed that in yet, but for sure I will be using the Beast SunShell as they do not break, not the Sonnax SmartShell Heavy Duty Reaction Shell (which is still an improvement over OEM, but not as good). It will include some Sonnax stuff, just depends on the budget I decide for the...

    H3 Alpha mods.

    You do not need too pull the intake manifold or heads as you just upgrade the springs to LS6 springs. They can easily withstand .550 lift and the small increase in durations. They should last as long as the OEM springs do with the OEM cam. When you get aggressive with cam lift then spring...

    H3 Alpha mods.

    You can get 400HP (or so close it does not matter) reliably with your 5.3, no supercharger, no repeat Transmission replacements or T Case issues. I cam swapped my 09 Alpha off road, with our Air Doc Intake, a SuperModulation PP TB and SFan 4500 w/digital control, MagnaFlow Cat back and a hefty...

    H3 performance Tuning recommendations

    Get an Efan conversion, Intake, Port/Polished TB, Cat Back Exhaust and then the tune from PCMofNC so they can tailor their tune to make the most of those mods as well.

    Transfer case?

    Front Axles replaced with what? When was the last time the T Case fluid was changed. When was the last time the Trans fluid and filter were changed? When was the last time the front diff fluid was changed? Same question as last one but rear diff? As others have suggested, sounds like your T...

    H3 Alpha rebuilt about 30k miles ago...seems sluggish

    A stock LH8 5.3L with no performance mods in the FT 4X4 heavy brick shaped H3 is not (contrary to what some may think) that huge of an improvement over an I5. It does have a wider band of power, but it ain't exactly gonna tear it up. If your cats were clogged it would be showing the code(s)...

    2/4 Band is Shot in my 2009 H3T

    Welcome fellow Mitten Dweller! Call Fred (senior or junior) at Midway Transmission in Roseville. Get a price from them, that is where mine will be going when it is time. ;) I look at it as an opportunity for some aftermarket upgrades, like Beast Sunshell etc...

    This forum software is glitchy. Tells you there was a problem with a post, try back later, you do, then get multiple copies. Uuugh! My driveway has a slope, but I back in up against the Garage door so the front is lower.
