Hey guys I have a 05 450 and I put 26" ITP 589's on it. I have no problem going forward in low gear, it can spin all 4 tires without much problem, but in reverse it won't spin the tires. It sounds like the engine is powering out. I was wondering if anyone else has had this issue and what they did to solve it? I have 300 miles on it and it has excellent power but when I get stuck and need reverse it won't do it.

 

Try using the override button.

 

Youre probably hitting the reverse rev limiter.
This was posted awhile ago, and is good info on it,

That would be it, Thank you Hondabuster.

 

Remember guys that the overdrive button does not do anything when in reverse. It only works when you have the difs locked and moving forward.
