I have an 02 chevy duramax with a ppe standard set on 4 straight piped exhaust ppe booet increse valve,a modified intake w/kn filter, and a bully dog propane inj system. My problem is the trans will go into limp mode if i either roll into the throttle at higher speeds, or when im in the throttle at around 70-80. It will jump into third and stay there until i shut the truck off. I cant figure out how to read or clear the codes with my ppe. Any ideas on what i should do to keep my from goin into limp mode

get a suncoast

dont mean to b stupid but suncoast what?

I don't see where you live but before you buy talk to Mike L on here. He will be straight with you won't find a better allison man

ok yea i am new on here thanks for the info is there any thing i could do like a shift kit or trans controller i dont have the cash for a new trans right now kinda on a budget for now. I am going to get a fully built trans in the future but not right now. just lookin for somethin to get me by now reasonably. again thanks for the info.

where are you located at?

south florida

well first off fill out ur signiture:) then take away some of the power ur adding and figure out how to reset codes with ur ppe cause one it slips once its gunna do it more and more frequantly till a new tranny is installed i am not the one to say if a shift kit would as i dont know

ok thanks for the advise about a monh ago was the first time it threw a code, now it seems i could do it on demand. i just cant figure out how to read the codes all it shows are xxxx where the code is ill just try and call them i think im doin it right im following the directions.

what year truck do you have? You could have gotten by with some easy upgrades but now that you've limped it so many times you'll need a full rebuild. I'd say to back the power way down and start saving money for some trans parts.

2002 ok thanks for the info the truck has been good to me for the past 3 yrs nothin major has ever gone wrong but it cant last forever right im at 199000 right now maybe i was just askin to much outta her
