I'd love to have on of these, but never really had a "need" for one. Maybe one day GM will start making them again AND maybe I'll have a "need" by then. They look awesome!!

Yes, GM is going back into the medium duty market. This time, they will only be sold under the Chevy brand. Chevy-badged Isuzu NPR's are due later this year, and the joint-venture GM/Navistar trucks are due in 2018. Stay tuned.

Hey Guys, just joined this site. I'm looking for some help with my 1995 topkick lowpro. It has the 6.0. I put a new ignition cylinder in it and a new battery. It started right up. I turned it off and tried starting again and it wouldn't turn over. So pulled the starter out thinking it was bad. Had it tested and it was bad. So i put a brand new starter in it and the same thing is happening. There's power all the dash lights come on but it won't kick the starter over. Any thoughts? I appreciate it. I'm mechanical but electrical is not my forta.

Check the fuses, make sure the battery cables and starter connections are tight. Also make sure the ground between the engine and chassis is good too. Maybe that new starter went bad?

I have a 1992 gmc topkick with the manual e brake was wondering if anyone knew where it goes? I ordered a 84in cable. Someone wrote on the door thats the length but it was cut off when I bought the truck

Can anyone help me figure out my c5500 . Bought a c5500 box truck (EX-UHaul ) for cheap . 8.1 gas with Allison 2200hs (unsure) . Part # Plate is missing from the transmission… I was told it has a 2200hs called dealer they don’t know ****** . Anyways , truck runs good trans doesn’t engage after previous owner brought it back from shop that did tune up , fluids and filters plus radiator replacement. Next day he started it and the symptoms were neutral in every gear . I checked the trans dipstick and it smelled burnt and didn’t look like atf. Looked like motor oil . I’m planning on servicing it this weekend.

I let the truck warm up for about 15 min and it seems like it wanted to engage forward and reverse but felt like it had no atf . That’s why I’m think they put the wrong fluid .

Thoughts ?? If I need a new trans can I use the Allison 1000 !!?
Thoughts !!?
