i was testing my new gauges yesturday when i floored the truck around 70mph the truck didnot down shift like normal but at about 95-100 the tranny just lett go and i red lined i put the truck in neutral and back in gear and it worked fine any ideas

That would be a limp. This needs to be moved to Trans Talk.

Done :hello:

codes ? check engine light ?

 

[duramaxloui]

how bad is a limp for a truck i have heard alot about this and never none the extent of damage

 

[duramaxloui]

no codes no lights, and i have had a limp before and this seemed nothing like it

a limp is when the trans senses a clutch slip and disengages before further damage is done . it will limp easier ,and easier after each time . but if the power is turned down it will operate like normal usually . wich is why most say turn down the power or get the trans built .

no codes no lights, and i have had a limp before and this seemed nothing like it

i would scan it , sometimes you pop codes and the MIL wont show on the dash . it can not limp without a code . the code is what causes the limp ( or disengagement)

could be a 1093 since he was full throttle at such a high speed

Wouldn't he have to shut it off though for the 1093 to go away?

seems like i had to , but i had to for a slip also or i was stuck in third gear . never tried going to neutral .

 

[beach_33]

i always had to shut mine off to get the 1093 to go away. it would still run just not well

"Zing" IIRC (been awhile...)

Which is prelimp.
Better start saving for and read-up on aftermarket tranny upgrades!

 

[duramaxloui]

ill check my codes agin i havent cheecked them sence i turned it off but thanks for the input

 

[dbtravis]

mine did that, shut the truck off for 5 minutes and it drove fine. other then that annoying light

that happened to me yesterday. i was racing a porsche and it kicked into what i though was limp mode, so i started to slow dow to pull into the shoulder and it all of a sudden fixed itself and shifted back into 5th... so i kept it moving. no cels or codes.

then again this morning goin to merge onto the parkway it actually went inot limp mode. i had to pull over shut the truck off and wait 30sec for it to go back to normal. i started it back up and had a cel. then kept it moving again.

 

[duramaxloui]

well i havent had a limp mode in a long time but my tranny seems to be running a little warmer than usual i was wandering if anyone has one of those magnet oil pans and if it actuly reduses temps
