Hey i was out doing some offroading today and i made the dumba$$ mistake of running really high RPMs while in 4 wheel low and the 4x4 low is messing up by ranomly jumping and not shifting properly.

Thanks for the help!

 

What do you mean by jumping? Is it going in and out of 4x4? FWIW I have run up to 6500 rpm in 4Lo and never had any t-case problems. When I play in the Dunes I am constantly running in excess of 5000 rpm.

thanks for the help, but after i waited a few hours i tried the 4x4 low again and it seems to work fine.

thanks!

 

Me too! I've been right along side JMC at the dunes WOT riding the rev limiter in low range... Never had an issue...

Maybe your tranny was over heating.

 

It's less likely his trans was overheating in low range.... low range reduces the stress on the transmission....

If it's an auto, and you had it floored, it's possible it hit the rev limiter before it shifted... If the trans is sluggish in shifting, it's quite possible to hit the limiter before the trans shifts, and that'll feel like a buck as it cuts fuel and spark, shifts, then powers back up... it's happened to me a few times. It's not hurting anything...

Maybe I'm not clear on exactly what it was doing? 'Jumping and not shifting properly' is a pretty vague description of what it was doing....
