Seen freind at work have not seen in a while. Bought a chevy dully few yrs back. Said had to put new or rebuilt allison 4100$ and now has head problem 3100$ i guess one side. Vehicle has 125,000 miles. Not to bash any brand but man that sucks. If Dodge dident have cummins then there wouldent be any Ram trk in my opinion.When he was looking said my dodge 92 has 300k on it.Dident want to here it, bought the chevy.Now he is thinking again:S

Troll.And BTW, if your 92 has a #52 block then it's got a good chance of splitting and becoming junk - not even suitable as a core.Every brand has its issues and it's foolish to bash any one company.

#52 block then it's got a good chance of splitting and becoming junk you meant #53 block... and it was 1999 to 2001 MYs, that had issues and out of those, only some had issues, not all trucks with the cummins fell victim to the 53 block.

My duramax has over 527,000 miles on it and just top 10,000 hours.

Gotta love it. You want to extrapolate from one person who bought a Chevy truck and your experience with a single Dodge truck and make a statement about how dumb it is to by a particular brand of truck? Now that is dumb!

I'll just keep my 7.3. Tows well and no issues till today. @ 157K the cps finally gave up. Had a 10mm wrench & Ford cps in the glovebox. 15 min and was going again. Gotta love the CTS. Read codes and there it was. Would not want to be without that monitor.

Just out of curiosity's sake, what does it cost to get the Allison rebuilt?

I want to say that it is about $1500. I saw a mention of it on the Duramax Forums once, they were talking about making it bullet proof.....to tell you the truth, that is much cheaper than buying a new truck....

Maybe for the parts, most auto rebuilds run $2,500 to $5 ,000. Allison is a "truck" transmission but $1,500 seen really cheap.

It cost me nearly that almost eight years ago for a stock rebuild on a 4L60E. I would expect a $1500 "rebuild" on an Allison will get you a very nicely-detailed take-out from a junkyard!

The 6.7 Cummins was implied with the 5.9 Cummins. I would have to agree the 6.7 is much more problematic than the 5.9. After all the different ford engines were singled out. I would put the LBZ Duramax at the top myself.

The GM trucks come with an Allison 1000 series seem to be reliable if the truck is kept stock. Any type of tuner or "racing" will reduce the life of the tranny. I tow about 12,000 lbs and never an issue. Run TranSynd fluid and change the external filter as recommended.

Previous D/A - 2004 GMC and 2005 Silverado.

Yeah, I just looked at Merchant Automotive. The upgraded Allison 1000 kit is $1900, plus you would need to have someone do the install....so probably in the $3000 range minimum.

$1500 trans rebuild???? run the other way. I would not want that one with the trailer in tow on 9 miles of 6/7% in the heat. Can't be a quality job.

Well to say the least very unusual!
I would say that in order of reliability best to worst would be
Cummins
PS 7.3
Duramax
PS 6.4
PS 6.0
PS 6.7 too new to rate

Doning Fire suite.

I would put the 6.7 cummins between the Duramax and the PS 6.4.

There's no way the 6.7 cummins is reliable as the 5.9 cummins.
