How Do You Pass People?

[Rzrman328]

So how do you get around people with a quickness.

I don't.

When you manually downshift, the transmission will be in 3rd (5 speed) or 4th (6 speed) gear before you go WOT; when you let it manually downshift you're already at WOT before the computer tells the transmission to downshift from 5th to 4th to 3rd (5 speed) or 6th to 5th to 4th (6 speed). The reason WOT is the issue is the transmission is trying to transfer the torque from the engine through the 2C clutch pack in 4th/5th which doesn't have the same holding capacity as the other clutch packs and any amount of slipping will glaze the clutches.

When you really romp on it with some power you can do some amazing things to the internals, see my pics below.



Mine was built my Mike at L&M Customs in Delaware but Jerry at True Street Performance is also building decent 545/65s that have been holding up.

ATS tried to build a 545 a long time ago and it was nothing more than a glorified stock trans that people were blowing through faster than the junkyard stock transmissions. Now they're saying you have to use their controller which is what they were saying back in the day, only time will tel with ATS but I doubt it'll be a bulletproof trans.

I don't think I'm letting my trans downshift on its own at more than half throttle after seeing these pics. Wow.

I don't usually let my 6 speed down shift to 4th unless I'm passing on a huge incline or I have 50-70mph headwinds

On many of the highways I drive the passing zones are only a few hundred yards long so that is not an option.

I think a rapid auto shift from 5/6 to 3rd slips the torque management?

If you manually stick it in 3rd before passing the management can do is thing. I could be wrong.

How do you pass people? ..........Now what kind of questions is that......WITH YOUR HEMI!!!! LOL

if its 30 mph or below i usualy pass them sideways but above 30 i usualy suck a little paint off when i go by but i have an 8 speed so i dont worry about the trans.

Mostly on the right... less oncoming traffic there.

I knew posting this i would get some smart ass answers, I was just hoping they would be a little more clever.

 

[huntergreen]

Yep, pedal to the metal.

i was dead serious except the sucking the paint off part

Clever like mensa clever? "By adjusting the velocity of my vehicle to complete the intended maneuver in the available space and time, followed by the use of a turn indicator and a flash of the high-beam headlights to announce my intention."

or Backwoods clever? "I make the ol' lady hol' my 40, than I mash on the long pedal! Hang on Mabel, wesa goin' 'round!"

Thats better.

Thanks for all the positive feed back from people, was looking more for technique that people use in order to save their transmission.

With a 545RFE it takes careful planning. I have to poke the (-) button until my dash says 3rd gear, which takes several tries because I've about got the button worn out, then I give it a one-thousand-3 count and then I go for it. I don't want my crappy transmission to crap out and make me have a crappy day and wind up with a crappy bill for another crappy transmission.

Can an 8 speed be mated to a 2009? Stock PCM to tune the engine and swap a new TCM to tune the trans. Kind of making the truck a mutt, but could it work?

Idk but I'm about $600 in parts from yanking the 545RFE out of my '11 2500 and putting in a G56 6 speed manual from an '06 2500.....I have the transmission, transfer case, pedals and hydraulics, need flywheel and clutch because the ones that came with were bad from sitting outside.

 

[MANual_puller]

Thanks for the info. So what is the difference between down shifting manually and allowing the transmission to down shift on its own?

Timing. Basically (most)auto transmissions are tuned to slip both the engaging and disengaging clutches on a shift so they "feel smoother" per demand from consumers that don't understand that saving their $2 latte kills their $2500 trans. At WOT the engaging clutch continues to slip because the slip was already started during the shift. When you shift manually at lower throttle it gets fully engaged and stops slipping before you lay the hammer.

Wow I'm glad I came across this, when I pass people on the highway I let the truck downshift on its own with about 50% to 100% depending if I'm trying to show off or not. I will say, with just a muffler, intake, and HemiFever, it will kick the wheels out if I try to get past someone while yelling "HEMI POWER!" or "Slingshot Engaged". Looks like all of that will be coming to an end.

Does anyone else get this "dead zone" when accelerating on the highway and the rpms don't move but the MPH increases? It happens around 1200rpm when I'm cruising and trying to slowly increase my speed.

This has happened ever since I bought the truck so it's not from the showing off

 

[Backwoods]

I don't get that but I will sometimes get an actual drop in RPMs by about 2-300 then they will go up again then shift.

Torque convertor lockup and unlock. It slips a little unlocked and has to unlock to shift. This is normal.
