GUNNER Posted October 10, 2003 Report Share Posted October 10, 2003 Has any one tried the quarter in tow haul mode? I know torque managemnt is reduced (not eliminated) in tow/haul mode and was curious to see if there was any gain. I street raced a dodge durango one day and we were on some very turny roads and he was right on me , I switched to tow haul mode and was able to start to pull him coming out of the corners. This was with my z-71 ext cab 4.8 3.73 gear ( I know not an SS, just seeing if anyone else saw an improvement or not) Link to comment Share on other sites More sharing options...
blackhawk Posted October 10, 2003 Report Share Posted October 10, 2003 Others say otherwise, but I did .3 better in the ¼ using the tow/haul mode, so yes I think it helps with the Torque management issue. Link to comment Share on other sites More sharing options...
GUNNER Posted October 10, 2003 Author Report Share Posted October 10, 2003 I knew it thanks Blackhawk. Basically if you are poor like me and cant get a chip use tow haul its a little better. I work on these vehicles all of the time and cant afford to do crap it sucks! I've put on 2 superchargers, tons of headers and so on. Maybe someday I can put thses things on my truck, for now stock will have to do. ( my stock is a 2500HD rc 6.0 4x4 I know dont laugh). Link to comment Share on other sites More sharing options...
blackhawk Posted October 10, 2003 Report Share Posted October 10, 2003 A buddy of mine at work has the same truck, how’s your gas mileage? He gets around 9-10mpg…ouch! Link to comment Share on other sites More sharing options...
GUNNER Posted October 10, 2003 Author Report Share Posted October 10, 2003 I get around 11 - 12. The problem is they weigh a ton (no pun intended). The 4L80e is about 50 to 80 lbs heavier than the 4l65e and then you have the larger frame very heavy. Link to comment Share on other sites More sharing options...
m396 #00-011 Posted October 10, 2003 Report Share Posted October 10, 2003 I've also noticed mine shifts about 500 rpm quicker in Tow/Haul mode, keeping the SS in it's powerband better. This might equate to better track times depending on mods for some too! Link to comment Share on other sites More sharing options...
Lee Posted October 10, 2003 Report Share Posted October 10, 2003 I read someplace that we are not supposed to leave the vehicle in the tow/hall mode unless actually pulling something. Was that misinformation? Link to comment Share on other sites More sharing options...
GUNNER Posted October 10, 2003 Author Report Share Posted October 10, 2003 If I remember right the owners manual does say that but I think it's because it says it will have a negative effect on mileage. Link to comment Share on other sites More sharing options...

Was that misinformation? That would be my guess to Lee, just negative effects on mileage. The only other thing I could see, would be that it decreases Tq management, so possible more wear on the tranny. Link to comment Share on other sites More sharing options...
GUNNER Posted October 10, 2003 Author Report Share Posted October 10, 2003 you might actually see less ware in the transmission because the trany is shifting faster therfore its locked up more less ware and tear. Usually a trany with a shift kit will out last a stock one, because it shifts faster and is locked up more. Just my 2 cents. Link to comment Share on other sites More sharing options...

Usually a trany with a shift kit will out last a stock one, because it shifts faster and is locked up more. Just my 2 cents. I knew this would be a sticky point, and hard to call. I think less slipping between shifts will lengthin the life of the tranny, but reduced Tq management could cause the opposite, more Tq to bang stuff around. For the record, I'm reducing Tq management, and adding a shift kit. So much for the life. Link to comment Share on other sites More sharing options...
GUNNER Posted October 10, 2003 Author Report Share Posted October 10, 2003 Go for it! You didnt buy an SS to just get groceries. You drive a truck like mine for that. Link to comment Share on other sites More sharing options...
Lee Posted October 10, 2003 Report Share Posted October 10, 2003 Thanks, guys. Well, mileage aside then, leaving it in 3rd gear has a big effect on performance. I was really surprised when the owners manual said you could do this without adverse effects over the long term life of the vehicle (other than mileage, obviously). I drop it down into 3rd all the time if I'm zipping through heavy traffic and I want extra power without punching it down into passing gear. Many times passing gear is too much in heavy traffic.

TimB Posted October 10, 2003 Report Share Posted October 10, 2003 I ran better times in Tow Mode. Westers uses tow mode as a performance mode. Link to comment Share on other sites More sharing options...
