so this is the 2nd output shaft ive broken and DMC transmissions has a warrenty so its not like i have to pay anything but turns out i was running 90 psi in 1st gear on the billet servo and now im only running 81 which i guess is regulation....this all sound correct?
I had the same issue over and over ,then i sprung for the billet output shaft and havent had an issue since.I also broke a few input shafts.these trucks put alot of stress on these trannies.psi sounds kinda low if you ask me.Ive had it all the way up to 160 b4 and yes 160s high.
I have never seen one broken ever in person. How you people do this....LOL.
I'll ship you a bunch if ya want :dancenana::dancenana: LOLQuote:

I'm not saying it's uncommon just that I haven't had one yet.
holy crap 160!!!! wow how was that shift like? wow at 90 psi i could cherp the tires at around 4grand damn that must be a hard shift though
Teeth chattering
thats why they are breaking...hard shifts...Quote:

Yuppers. That'll do it every time. Keep the pressures stock. If you want firmer shifts, get a shift kit.Quote:

Agreed!
i have a competition transgo shift kit
Then you prolly need stock pressure settings in the tune.
which would be 81 PSI right
Don't know. GM doesn't give shift PSI specs just PCS PWM amperages.
I broke 2, just like this...

The second one, I was 1300 miles from home. Need less to say, I have a 4l80e in the truck now :D

Heavy trucks,hard shifts,good traction.
