Rear end problems behind Aisin?

mgood777 · Jul 12, 2015

I am on the verge of buying a 2015 3500 with the Cummins/Aisin combo. Just for giggles I asked the dealer to price out a 2016 for me. What I learned was that starting in 2016, the Aisin can only be ordered with DRW. He said it was because there were rear end problems in SRW models behind the Aisin. He said the Aisin's were too strong for the SRW rear ends. Apparently that's also the reason why the 2016s are getting a torque increase. They had to beef up the rear ends and to make sure people don't have problems that's why you have to now buy DRW to get the Aisin.

Anybody know anything about that?

that's a first.. " a tranny that eats rear ends" I would put a call into Chrysler and try and get some one at the ram division, try and get a little bit more information. 800+ foot pounds of tourqe is a lot for anything to handle, but the rear end/gear set should be able to handle what ever these trucks can throw at it.

I would think if its that close to the ragged edge, every truck that has larger than stock tires would be fighting rear diff issues.

As far as I know there were no warranty issues on any of the 11.5's for either GM or chrysler. They have been pretty solid for years now. If it was truly an issue they could just stick the 11.8 in the srw trucks.

IF there is a potential issue, it could arise from the lower 1st gear of the asin combined with the increased output for 2016.

Back in 1969, the 440 'cuda only came with an automatic because Ma didn't think the 8 3/4" would handle the abuse from a 4 speed.

Yep!

Considering there are guys doing boosted launches all the time with 1,000+ lb/ft deleted 6.7s and then towing with same set up, I don't see how it would be an issue. If they do stop putting them in the SRW, I think it would more likely be due to higher cost/lower sells than the 68.

I posted this question to a forum on another site as well, and so far the responses have been pretty similar everyplace. Thanks for all the input.

Not all. Some of us need to actually use our trucks.

As far as the topic goes, I don't think that salesman knows what he is talking about. Then again, most car salesman rarely do.
