    H3 Transmission dead?

    wow. So I was trying to get a trans from LKQ from an 08 Avalanche. Still a 4l60e. I called them and apparently there is no family match for the hummer. Ours is a different model of the trans. This is shit. What do I do? And the shop said my transmission is definitely bad.

    H3 I CANNOT Tow apparently

    that all makes sense. Just not to my brain lol my i5 on monster tires shouldn't be more capable hahaha and I also won't pretend to be a towing/camping expert. I've only ever towed with my supercharged titan with airbags, active suspension, level 10 transmission, cams, etc. That truck is a...

    H3 Transmission dead?

    I appreciate all the advice I can get. And I actually have an Autel, funny you mentioned that; just not their fancy one. I didn't know that the tech II was that capable. I hate intensive transmission/transfercase/engine work. I can do just about everything else. Haven't gotten a call from the...

    H3 Transmission dead?

    Scangauge II was what read that. I also have another fancier one that does live data and abs/srs info. Although I don't know how to use it to it's capabilities

    H3 Transmission dead?

    I always search multiple variations of my concern followed by forum. I’ve called a few places today and the soonest availability is Wednesday. Apparently a good shop. Any concerns on google reviews had well written responses with proper grammar. I care about that lol I wouldn’t even say 1-2-3...

    H3 Transmission dead?

    It’s funny in a not funny way. First gear fine. It shifts into second and then just goes as high as I let it. No power. 20-25 mph max. Fluid is fine. I was told it was changed before I bought it and the carfax says so too? I’m thinking trans shop. I thought that too. Torque converter or...

    H3 Transmission dead?

    So today, suddenly my transmission is slipping horribly, can’t get over 20 mph. Give it throttle rpm’s shoot up. Put it in 4 hi lock, worse. Couldn’t get home due to all the fckin hills in Albuquerque. Had to drive to my dads work and wait for him to let me park in a locked area. Embarrassing...

    NM is weird. I’m happy you can concur. My camping route takes me to 7000’ so I’m thinking it just wasn’t feasible with the trailer. It’s all ok since I know now.

    H3 I CANNOT Tow apparently

    eh, I don't want to re-gear. I do have a truck that can tow around 10k lbs. Just need to replace the wheel bearing/hub. I think I drastically overestimated the towing of the Alpha. I fully disagree with the 6k lb max. tow/haul is massive for every truck I've towed with. Again, today...

    Wish I had info on my Alpha. It has an air doc and hunner skids. The person must of been a forum member or at least lurked. There's probay more done to it than I know.

    H3 I CANNOT Tow apparently

    Absolute investigation is needed. I have an Air Doc intake as well. Yes the nittos are 81lbs each and I have 5. I have a dual exhaust as well. Your Alpha seems to have much more than mine! NM sucks sometimes. 7-8000ft elevation, 6-7% grades. Add that to whatever is up with my Alpha and it was a...

    H3 I CANNOT Tow apparently

    there aren't any classic signals of a clogged cats. today driving into work, 64 degrees outside, an hour, stop and go the entire way. Highest engine temp 193, trans got to 176. Not a whole lot adds up. In horrible temps I'm hot which might make sense. Towing destroys me. Maybe this is all...

    H3 I CANNOT Tow apparently

    I truly appreciate your feedback. I didn't imagine my setup was that bad with the V8. I more so imagined the other GM setups and picked the lightest travel trailer I could find. My first h3 was an i5 with a solid axle swap, spring over rear and 37s. I could pull a 1200lb popup with a mastiff...

    H3 I CANNOT Tow apparently

    Exactly, no tow/haul mode. Even with the Longhorn Ram, if I forgot to use tow/haul I knew it on those big hills. So weird. I have realized that the radiator and trans cooler aren't the best either. Don't know why I had such high expectations lol

    H3 I CANNOT Tow apparently

    I have 35x12.5r18 on there. Nitto Terra Grapplers. Not much gear at all and the trailer was dry. I do however have 2 great danes, one weights 100lbs and the other 120lbs. Very basic loading in the trailer. One bag each and an ice chest of some drinks. My parents have an RV and I let them take...

    H3 I CANNOT Tow apparently

    Just so strange. The Alpha was maintained wonderfully. Carfax showed tons of dealer services done on time, etc. Looks new inside and out. 118k miles. Clean engine. No leaks. And sadly, it wasn't even in the upper 90s yet, 76 degrees outside maybe. The route I have to take to head north has many...
