Haven't seen 5.29s for the AAM 10.5 or 11.5 rear end, I know Yukon makes a 5.38. But I've been reading for a couple years that the diesel guys can't find anything larger than 4.56s for the AAM 9.25" fronts in 2500/3500 trucks. Could be though, since I don't have a SFA truck anymore I don't keep up with it like I used to...

 

Curios to the gears in the truck as well. When I was researching gears for my truck, due to lack of knowledge and running 40's, thought I would have 4.88's installed. I learned(or thought I learned) 4.56's were it, so went with those and down sized to 38's.

 

i looked also, 5:29's are not available, dumb me took a car places word for that.... stupid. well anyways how do I go about telling whats in there without taking the cover off... it looks to have never been apart so im thinking whatever factory was in there thats what they are

 

LOL....a Megacab with 12" of lift and 41" tires and stock gears.

Yeah, that combo might just kill a transmission.

With you having changed tires, are this point the best option to find the gear ratio is to stop by the dealer and have them pull up the build sheet by the VIN number or send an email to Chrysler

 

Nice looking truck! How much get up and go does it have with the Hemi powerplant?

 

Probally not much, if it has the stock gears

 

Yeah, a Megacab with 12" of lift and 41" tires and stock gears is NOT a good thing.

 

so im having the truck hooked up to a good codereader/laptop today to see if the tcm is working correctly or if its the shift selinoid, ill keep you guys posted later today

 

That's a sweet truck and I sure love a lifted mega but with stock gears and 41's you must be getting about ten gallons to the mile lol.

 

he couldnt read what i needed read, i guess im gonna have to take it to the dealer, ugh! any other ideas or anyone in my area that has the capabilities to do this??
