Hi

I just picked up my first 4X4 truck last month. I just tried the 4H in a rain storm last weekend. When I slowed down to pull into the gas station it started to bog down like the gears where too low. Like going in too low of a gear in for your speed.
It felt like the engine was stalling out also.


Is this normal? or did I do something wrong? The first time I put it in 4H which was about 5 minutes before I was stopped (not knowing you needed to be driving to change it over).

I want to try it out again but I'm afraid of killing the transmition. Its an 03 screw.




Thanks

 

I'm guessing that even with a wet road surface, all four tires had sufficient traction to put your driveline in a bind due to being in 4wd. Typically you shouldn't run in 4wd on pavement, especially if you need to make a turn at the same time.

I make the point about turning since you mentioned pulling into a gas station.

You could try your 4wd again, on a slicker surface, and it might not show the problem. You could safely try it again on pavement, for a short distance in a straight line.

 

Were you turning?

Unlike All Wheel Drive cars, a Four Wheel Drive truck has no differential in the transfer case to split the front and rear axle. In a turn the two axles turn at different speeds and cause binding. Mud, snow, gravel, dirt, ext have enough give to let a wheel slip releaving the tension. Wet roads sometimes don't, and for sure never use 4x4 on dry pavement where it is easy to break something.

I rarely use 4x4 if it is only raining.

Ok thanks for the info guys.

Yes I was turning.

The reason I was trying the 4WD is because the first week I got It I fishtailed in the rain. I think It was mostly due to my driving habits.

 

4wd is not for the rain/wet pavement. It's for OFF road.
