Maybe in the special Olympics...
Hanging shifts out to dry while accelerating and downshifting so far when coming down any sort of gradient until you either pull the trans into neutral yourself else leave it alone and wait for the BOOM into 5th or the inevitable ba, da, ding, ba, da, ding red popup window alerting you that you are now under reduced engine power due to low engine oil pressure....... is the kind of trans I would nominate for the special olympics category behind a 6.7!
An Eaton Fuller 9 with a hole cut in the floor and big goofy ass shifter where the console used to be would be a HELLUVA better option!
Run FASTER unloaded too because it wouldn't leave the engine out to dry all over the limiter for a 3-5 count on each gear with the converter unlocked.
Loaded, it would just STAY IN GEAR.... what a concept.
And no..... you can't use the shift buttons and manual mode because the delay on those buttons is about 3 times longer than the actual time the engine should even be in a single gear up to about gear 7. So 1,2,3,4,5 for sure all need to happen in the time those buttons would accomplish the ONE-TWO shift, while just sitting on the limiter blinking the number 3, 3, 3, 3......... and then finally going to 3...... hanging up on the limiter for a 3 count while blinking 4, 4, 4, 4..... meanwhile you have pressed the upshift button 1568 times at this point....
When the trans shifts while the truck is FULLY LOADED at WOT it is FIRM, CRISP AND RIGHT NOW on each and every one, skips no gears and shows that the trans is NOT THE PROBLEM. The hundreds of tables and the morons writing them into the TCM are. If there were a PCS for the 10R and a way to tell the 6.7 ECM to STFU about the trans, you could have a hell of a unit. Until then, you have a flaming piece of commy shit with no throttle response trying to wipe the bearings out in the engine and snap something in the trans if you allow it to downshift from 10-9....9-8......8-7.....7-6...... and you don't intervene at that point on the high side of 3500 rpm..... it WILL go for the 6-5.... and BOOOOOOM!
NO.... WAY.... it could do that shift more than a few dozen times before you were walking....
Driving this truck is like riding in a semi with a kid trying to learn how to drive who just keeps over-revving each shift until you're totally off boost, up on the governor, the load has shifted and now he's bound and can't get it OUT of gear.... then finally does only to get into the next gear so late that he's immediately again on the gov.... bound up.... another KA...KUNG out of gear and CLAAAAAAAAASH into the next one with a huge jarring deceleration because again.... it's too late for this gear!
Difference is..... the kid LEARNS and stops over-revving and being a moron.... the 10R180 DOESN'T! In fact.... unless you clear it and disable learning, it will learn itself into the most retarded shifting imaginable. At least imaginable for someone who has driven the pos. Beforehand I wouldn't have been able to imagine a shift strategy THAT RETARDED!
Trans seems fine. Strategy is junk. I pulled everything down with HP Tuners and after looking through that abortion decided there was no saving it. You can change lockup strategy in one place, then you change the radio station and it uses a different map. You find it, then you put on the blinker and it uses another map still. Then you touch the brake pedal..... you guessed it.... abother map for that... then the inclinometer goes over xxxx degrees..... yep... another map...... turned on exhaust brake or tow/haul?..... another and another...... trans temp below xxx.... you guessed it..... another map..... to the tune of HUNDREDS of times...
It's an absolute miracle the things EVER actually MAKE a shift or that they EVER actually lock up at all! They have to make 687,362 decisions and turn 2 nuclear keys simultaneously in order to lockup.... and all that has to happen before you go 20 feet forward.... GOOD LUCK!
The 4:30 gear makes the delay problem painfully obvious. It is ALWAYS behind
