Allison 5sp: Slipping out of gear. Upshifts & Downshifts

[SSchmi5519]

Started doing this tonight. Never any problems before.

Trans is a SC IV w/ 5-Star converter done by Inglewood Trans. Has been in there and working perfectly for 25k so its not an error of that sort. It was built right.

No change in tune, etc. No loading new tunes of any sort.

The trans will take a nap in between each upshift and downshift.

The engine will free rev between each shift.

No codes, no limp mode.






Seen this before Mike?

Definitely not fuel related.

whats the fluid level at? when did you change the spin on last?

maybe the interal filter fell?

def. the trans builder... i don't trust that guy Mike L. No way would he ever get inside my trans :spit:

What were you doing with the truck prior to the slippage? have you check the magnet to see if there is any abnormal amount of material on it?

Fluid level looks good, did a new spin on about 4k ago. Might drop the pan and check that internal filter.

Only thing thats really changed in its driving environment is that it is getting down to the low 30's here at night.

It started doing this right out of the driveway tonight. No issues with it this morning.

Will do. :thumb:

I doubt the cold would do it. Mines been in -temp a few times and always shift smooth (accept for that 3-4 shift issue)
