2012 Dodge Ram 5500 6.7L Cummins/Aisin AS68RC.
Complaint of the Trans not shifting, Random crank-no start, Cluster goes dead, Exhaust brake activates by itself randomly.
Had a bunch of DTC's, Mostly U codes for communication between modules, But U0001 "Can Bus C" was a reoccurring theme.
Just so happen to see a harness rubbing on the Trans Dipstick Tube & the split loom had rotted off, Found a needle sized rub through spot on one of the twisted pair of Can Bus circuits.....And the Dipstick Tube has the paint worn through causing a intermittent short to ground. Taped it up good & secured the harness where it no longer rubs on anything, Less than a hour in this one.....Wish they were all that easy!!!
1999 Chevy C1500 (GMT800) 5.3L/4L60E.
No 3rd or 4th gear, Pulled the trans & tore it down......There might be 4 parts that are reusable in the entire unit, Just worn smooth out!!
I'll tear down a core in the mourning. A storm rolled through preventing me from getting a core out of my Conex.
Building a 9" Ford differential for my dads '72 Olds Cutlass with a '17 6.2L LT1/8L90E.
Has a BOP 8.2" in it now with 3.73 gears. With relatively short 26" tires & the 8L90E's 4.56 1st gear ratio.....It will boil the rear tires off at will & the TCM likes to freak out & either shift way to early or too late.
2 series posi carriers for 8.2" BOP diffs are impossible to find used & no one makes a new one, While it's stronger than a GM Corporate 8.2".....It's still on the weak side.
My dad is a Ford hater through & through, So I recommended a Corporate 12-Bolt as used 2.73 gears a readily, But a 2 series Posi Carrier.....Not so much.
I finally beat him down by talking smack every other day about how the Ford 9" has no carrier breaks & the ONLY stronger differential put in passenger cars was a Dana 60 & the highest ratio available for them was a 3.07 which are also near impossible to find

.
Found a complete 9" differential out of a 1979 Lincoln Versailles with factory disc brakes & 2.47 gears. Having Quick Performance build a new housing to fit this A-Body & supply some 31 Spline Axles.
*Yukon 31 Spline Trac-Loc posi carrier.
*Strange Daytona Pinion Support.
*Couldn't find a kit with Daytona Pinion Bearings & seal along with 2.892" carrier bearings, So I bought a kit with 3.250" carrier bearings & have 2.892" bearings ordered.
*Yukon 1310 Yoke.
*Yukon Crush Sleeve Eliminator.
I tried checking the Pinion Depth before removing the Pinion & Support cause I really want to get these gear right back where the were as the pattern is perfect. If I was reusing the original small bearing Pinion Support.....I could reuse the factory shim with confidence.
Must of got 14 different depth measurements before I caught on that the end of pinion was not flat (Not even close)
Chucked the Pinion on my lathe & trued up the pinion end.....Reassembled the pinion back into the original support & was able to get a repeatable depth measurement.
In my defense.....I'm used to aftermarket gears with machined pinion ends & the recommended depth stenciled on the pinion.
I got the Pinion & Support fully assembled with near perfect bearing preload which takes some time shimming .002" at a time.
