When My truck shifts from 2nd to 3rd, under full throttle, I can here the belt slip. It happens every time in this senario. Whats the deal with this? Does it happen to anyone else. The only other mods to the performance is a K&N intake system.

 

If your running one of the Edge program Levels, it tightens the shifting.
On an old belt, the engine rpm changes so fast under the shifts that the driven assesories can't change as fast ie the water pump, the alternator, the power steering pump etc.
The belt slips a short time until all catch up.
Put a new belt on. If you still have a problem then back off on the shift firmness a bit.

 

It sounds like your belt is dry. check it for cracks and make sure the tensioner is still tight.

 

I don't think it is a old belt I have an 06 and I get the same. I hear some people beefing up the belts with a better one. I believe 1 was a gatorback type, brand , model unsure

 

I HAD the same problem on my truck and the company truck too....just change to a Goodyear Gatorback belt and the problem is solved! I have the Edge too and no belts slipping.

 

Mine slips too. The replies to a thread I had in 04 all said go with the Goodyear gatorback belt.

 

I've had a gatorback from day1, no slips from my belt any more.

 

This is normal with a tuner. It's been discussed numerous times. As stated above go by a Gatorback belt and it will take care of this issue.

 

Does the belt slippage affect performance? Will the gator belt cause the shifts to be firmer. I only ask because I thought the slip was normal and I kinda like it (sounds like a turbo blow off valve "alittle"). But if its hindering my performance it will have to go.

 

It's hindering the belt. Too much belt slippage=belt breakage.

 

exactly why after buying my truck from my dad, I put on a gatorback belt because I knew I was going to mod it. Works great

 

Anyone have a part number?

How about tips for installation?

I suppose it shouldn't be too hard for a rookie...

 

I got mine from autozone, sorry no Part#.

 

It is an 06, so I doubt the belt is too worn. I have the programmer set at level 2. I guess I will try the gatorback belt. Seems like it was the fix for everyone else.
Thanks for the replies.

 

My truck has the belt squeal any time it shifts around 5 grand and i dont even have the edge yet. my b-day is march 18 and i think im getting myself the edge/gatorback combo
