Trans slipping

[gr8white]

Last night I stopped to get something to eat and when I left out of the parking lot the trans felt like it was slipping.It was a slight uphill pull,you could hear the engine rev up but was bearly pulling.I let off the accelerator a couple of times and it quit.The rest of the drive home was normal and I drove the truck again today and everything was normal.I hope it was a one time deal.

Have you checked the Fluid level in the Tranny?

Not yet it's been raining all day.It shouldn't be low with only 2,000 miles on it.

that happened on my 08 while hauling my trailer. it just wouldn't go, it was a 10% grade up hill. i had to stop , shut it off then re-start. never happened again for the next 2 years

When you do check it take note of the Fluid Color also!

It should still look like it just came out the bottle,If it's slipping or not shifting correctly the oil will look dark,or even black like burnt Motor Oil...This would be a sign fo sho...

The log handlers we operate in the mill/Woodyard Eat up some Trans fluid,we run them around the Clock,with all the Functions of the Machine being hydraulic The Throttle stays on the Floor half the Time :~) The Trans is a 3 Speed with De-clutch ...

Fluid looks like Burnt Motor oil everytime they Change it ...

I had the same issue with mine. Never with a cold engine or tranny and only after a short lunch stop when everything was warm. It also only happened ones ....until the next time after a lunch stop. I have now 12K miles and i think the issue is gone! So no way to try to explain it to the service guys!

This happened to me last week some time, shifting from 1st to 2nd (no trailer or load in the bed). And it also happened today from 1st to 2nd. The truck only has 3000km on it.

I just decided to look it up on the forum to see if anyone knew the cause, or if there was a recall. But based on the amount of replies, it doesn't seem like a common problem.

I'll keep reading through the forums, maybe I'll come across something

There is not recall about this issue. I checked oil level with 11K miles and it was ok and like new. I had the problem bitween 10K and 12K, now I have 13K and the truck is running great. Never mentioned it at dealer ship. I still have the A/C issue which I posted under interior issues!

Mine has done it 4 or 5 times. I now have right at 27K on it and its done it from almost new till last week. I'm going to take it in and see what they say. did it last week on way out to eat and earlier that week comming off interstate coastin down the exit ramp. I was approaching the merge lane and gave it a little throttle and it reved up and then caught a chirped the tires. I'm sure thats not good but no damage as of yet, I hope. I could see where if it hesitated and you really reved it up and it caught I think something would break. Most ot the time its done it it was shiffting from second to third, this time i was coasting. I'll post what I find if anything

Since I did the tranny update from H&S I never had the slipping again....so I hope it was just a software issue.
