Much appreciative of the break down on the dt12 … especially for the people like my self who works on there own truck

[@jeremyashley1]

DT12 when pulling a loaded trailor 44k. I slow down to a stop light or brief stop (down shift). The truck accelerates from a brief stop. Truck jerks dives, stutters or sometimes stops especially up hill. The code "wont shift into gear" and " shift to neutral starter block", the codes rhen clear. Come to full stop shift into gear and drives fine. Only seems to happen when coming to a stop from a higher speed then accelerating like at a stop sign. The truck shifts fine when not loaded. Seems to happen with a heavy load so far.

Buen video go USA thanks

Is there a possibility of an internal air leak in DT 12 looks like I have this problem.?

[@cablanchette1]

I have a 2017 DT12... When I'm loaded, if I have my foot to the floor, there will be slipping in 10th 11th and 12th.... Usually at the lower RPM range of those gears, it'll slip for a second and then come back and grab and maybe slip some more, maybe not. But if I'm easy on it, it may not slip as much. It's hard to get it to do it bobtail. But it does still do it, if my foot's to the floor in 12th gear...... If I shift manually, and run the gears a little bit tighter, higher RPM, without my foot to the floor, and I shift into the next gear, the RPMs don't drop as low into the next gear, and I can avoid the slippage. Any thoughts?

What the clutch life on dt12 And what the system when it going to bad and there’s any way to check ?

[@et9151]

Are there any grease fittings on this transmission?

[@raheemgabbidon4911]

Is it safe to change the fluid if it's at 500,000 miles?

[@MichaelBrito-ls1vs]

Hey Steve, I have a DT12 on a 2017 cascadia evo I have started having a issue similar to what you are explaining on the video my dt12 recently started going into neutral while up shifting from 11-12 and more often while down shifting on low gears. When I arrive to a stop or red light it tends won’t go into gear just stay on neutral and I’ll have to switch to drive or reverse and neutral on the handle while it’s on neutral and trying to go into gear it’s making shifting hissing noise like it’s trying to enter but won’t enter gear at some point it’ll go into gear and on handle I’ll switch to drive or reverse depending what I’m trying to do at the moment , can that be related to the relearn ? I’ve added over 100k miles and haven’t done a relearn while doing pm service.. any thoughts on what it might be ?

I haul chemicals with tank surge. Do you recommend getting a manual over the DT12 Automatics? It's hard finding a 3-4 year old truck that has a manual transmission.

[@jawidehsani5347]

Hey Steve, my ABS light is coming on whenever I push the brake paddle It will be quick for a few seconds and then goes back off. It just happens when I have a trailer any recommendation thank you
