#23 of 42 Trans & Diff cooler 3500 ?
Dec 25, 2008 (6:55 pm)
I have a 2007 3500 6L auto that is the chassis for my motorhome. I would like to add extra cooling for the trans and rear axle.
I tried a deep pan for the trans but it looked like there would be less than 1/4" clearance as the exhaust crossover pipe runs under the rear of the trans pan.
Anyone know if there is a pan that will fit?
Also looking for an aluminum cover for the diff. Anyone know who makes a good cover.

could someone please tell me the differences between the h1500 and h2500 years 2003-2004. I've been looking for a 2500 awd and they are hard to come by. There are a lot of 1500 awd's available and some have suggested that only the rear springs are "beefier" I found a pdf spec sheet from gm which shows the same 6400lb towing capacity for both the h1500 and h2500.
Also if I get one of these is there a small lift kit avaiable for them? could I use the same stuff from the pickups?

The h1500 is the only standard model that comes in AWD.I have an 04 h2500 and looked into this for quite some time.The 2500 and 3500 are not offered in AWD,just the h1500.NOW,you can buy an aftermarket conversion from quigley motors in pennsylvania,they have used vans that are 25/3500 models and ford vans also.OR,you can convert your current 2wd to a 4wd or awd at a covnersion specialty company that puts in a front drive axle,brakes,shift componets,suspension etc.This will run you between 7500 and 10,000 bucks turnkey,meaning you bring it to them as 2wd,and drive away with an awd or 4wd for the cost of 10,ooo bucks.Dont even think of doing the work yourself,there are torsion rotation bars that have to be welded etc(messy) impossible.Check the web for offroad 4wd conversion companies that do vans if you want it done .there are many in most states.california,salt lake city,LA,phoenix are a few.Gm does not offer AWD for 2500/3500 vans from factory.In my opinion,GM has failed,and it is not an option other than the 1500.Towing capacity is both engine,rear spring and transmission related.Not just rear springs and shocks etc.

Thanks for the quick reply. I'm currently looking at 2 different 2500 awd's both 2003's, I know that at least one has 8 lug wheels, the other I have not seen up close yet.
I'm also looking at some other 1500 cargo and passenger/conversions and would like to know the real differences. I know you can not get the 2500 in AWD anymore, but the 2003's are the ones I am interested in.
I would love to convert my current van to 4WD but 10k is out of the question right now.
I wish GM made a 3500 155 wb AWD!...Too bad we can't get the Ford Transit in the states.

I d like to learn more about the 2500 awd. When I researched it, I found all advertised awd 2500's to reall be 1500's. Even now, when I do internet searches I find 135 inch wb 2500's awd? Thats odd, thats what my 1500 is.
I think if there was a true 2500 awd, it would have 8 lug wheels, a 6.0 and 4l80e trans instead of the 5.3, 4l60e. My 1500 awd also came with a tow haul mod, trans cooler, hitch. As far as I know of all the 1500vans came withthe 2 piston brakes that were an option on the denali and escaldes when they got the tow option.
The 2500 chassis, was never a torsion bar front end that I know of either. The frames are different.

Your headlight switch may be defective,the rotary switch on the lower left of the steering wheel.You may also have a headlight relay module thats defective.Those are located under the hood i believe.refer to manual for replacing.Since your lights are stuck on,that means the circuit is staying activated,and not being broken when you turn the lights off by the switch.

Hello to all , newbie on this site ,have a ? i own a chevy express 1500 mark 111 conversion 1998 5.0 vortec just did a motor swap out had a wiped cam so i found a good deal on e-bay for another 5.0 vortec with a LT1 cam the cam being the only difference of course with new rocker arms ,springs,locks,gaskets now that we finally have the motor in it does not want to start,now the snap -on scan tool reads out no injector pulse width so i am a little worried [,have had trouble in the past with no injector pulse],of course the dreaded pass lock issue,now i did by-pass the pass lock system a little while before i did the motor swap,but i wonder if the pass lock is my whole issue again,or could there be another solution here or how to go from here,any suggestions would be appreciated from the tech heads out there.
