Hello
probably it's a stupid question , but my SRT8 Gc did come without its owner manual , so I don't know if the following behaviour is ok.
I.E in full automatic mode (D) I downshift manually to 3rd and don't touch the autostick anymore.If I reach to a stop, I see the numbers of the gears on display , decreasing to 1st gear.Now I start from the stop but it wont upshift anymore until I manually do it. In other words, in manual mode, it downshifts automatically but doesn't upshift except You do it.
Is that correct? Or if I select i.e. 3rd gear it should also upshift automatically to 3rd gear and stop there until you change to fourth and so on?
Hope it's clear and sorry for my english
Thank You all in advance,
Giovanni

Giovanni:

You are mostly correct. I have "both" types of autostick. The transmission in my 300C works as in your later statement. If I have it in, say, "3", it will start in 1st, and shift up to 3rd, no further. If I stop, it shifts down to 1st and shift up when I take off.

With the SRT8 autostick (GC works the same as the autostick in 300C SRT8), if you put it into autostick mode, it will downshift to 1st when you stop, and then stay there unless you totally redline it out, when it will shift up automatically. I have not done that per se, but that's what the manual says it will do. Further, you should be able to start from a stop in 2nd or 3rd, but no higher gear. When in 1st, 2nd or 3rd, these are "start and stay" positions, meaning that you will start in that gear and stay in that gear (unless you go past redline).

Does that help? I hope so.

Good luck.

If you have it in any gear it will NOT up shift,even when you hit redline.Trans Always holds gear on the way up.

Excellent..

No It sucks.

It bouncses off the rev limiter, and makes your vehicle jerk like a dog humping your leg.

The shifting on the Auto-Stick leaves alot to be desired. It reacts very slowly, so unless you have a shift light, you will hit the rev limiter if you shift by ear. Shifting in this vehicle manually should be more precise, and less of an anticipation. The power band in the upper end is great, and the redline is a few hundred RPM from the maximum potential of the 6.1. Sad really

It sucks.

That about sums it up.

Understood. At least if you want to go to the redline, you can. Perhaps some upcoming electronics mods will get everything where we want it to be.

The SRT engineers last session on said they were preparing a new software flash that would give an automatic upshift.

There will be a service bulliten out soon. Very soon.
The real issue is that the engine out accelerates the electronics and the transmission hydrolics. The other issue is that there is some lag in the TACK.
Now, the service bulliten will also say that once the service bulliten is applied it cannot be removed.
To fix the issue we need to create an auto upshift at the redline because in this case the transmission electronics is smarter than the driver and allows just enough millaseconds to create the upshift. There will still be a manual upshift allowed below the critical speed needed for an upshift.
We also need to reduce selected double downshift windows in the calibration to minimize the rate of engine accel to allow a predicted upshift.
We have applied the change to selected customers with very positive comments.

They need to come out with a flash that will speed up the manual shifts. The shifts are way to delayed, it takes over a second. You gotta hit the shifter at like 5K rpm so it shift at 6.2k rpm. Its retarded, only good for downshifts going into turns and stuff.

Another pain is when in the manual mode you can't just up shift to Automatic mode. The only way around it is to shift the shifter up to netural and then back down to drive.

csmalls, you don't have to go up to nuetral to get back into auto. Just hold the slapstick towards the up shift a few seconds.

Thanks! I didn't know that.

I wish they wouldn't have bothered with this manual toggle at least it should be an option. I can't recall how many times I've bumped the stick to the left without my knowing it and then a little later you're like huh?

The way to go is SMT :D

Hello,
Thanks a lot to everybody!!
You 've been very helpful as usual.
I was a little worried because the autostick doesn't work like other automatics I owned i.e. in my 5.9 if I put it in 2nd gear it downshifted and upshifted normally without remaining stuck in 1st(I havn't still experinced red line upshifts in SRT8), and so it is for my other cars with auto trans.
By the way I like how the srt8 trans works (in manual mode)! It' almost like a full manual without a clutch.
Thank again to everybody.

Just hold the autostick to the right for a few seconds and it will revert to D (drive).

Actually, since the invention of the 727 automatic by Chrysler, automatics have been dominating super stock drag racing. The 727 was the first 3 spd automatic that could reliably handle the torque from Max Wedge and Hemi engines. Since that time there have only been a handful of superhumans that could manually shift well enough to compete with auto trans cars; people like Ronnie Sox and Billy Glidden. As much as we all think we can drive like a pro, leaving it in auto for acceleration is always going to be the fastest on the drag strip. The onboard computer thinks and reacts a lot better than we can.

Now, on the road course it's a different story. The autostick works great in manual mode and allows for shifting in situations where you can't normally shift if you have to worry about a manual clutch. On the 2.25 mile course I have been running on I leave it in 3rd most of the time, downshifting to 2nd on a few of the slower turns. The autostick really works well. It's also great on the mountain twisties here in the Rocky Mountains. All you need is a little seat time to get used to it.

That's a loaded statement.

In the 60's and seventies that may have been true. Sort of. A bone stock 727TF was (and is a great) transmission, but, without mods is very sluggish when you increase torque/horsepower. The same engine in the same car, with a factory 4-speed, or a factroy 727, my bet is on the manual. I have had both, and without a higher stall convertor and mods to the accumulator, valvebody, replacing the intermediate band lever, and possibly upgrading the discs and clutches, I find a manual faster.

A newer vehicle, let's say a Corvette, is quicker as a 6-speed manual than an automatic. A Mustang, same.

The advantage in a manual is in there being better first gearing, and tighter ratios, as well as less reciprocating weight, and less power loss at the wheels.

I never said they were bone stock or that you couldn't put a shift kit in. Based on modern Super Stock racing in NHRA, today, this century, right now, automatics are still and have been since the time I mentioned, faster than the manual cars. IMO, Super Stock racing is the ultimate acceleration test there is for door slammers. Super Stocks evolved directly from factory built cars even though now they only roughly resemble anything the factory ever built. But, still at the top of the Super Stock food chain is SS/AA which consists of automatic shifted, hemi powered '68 Barracudas and Darts followed by SS/A for manually shifted cars.

The point of my post was that the autostick isn't nearly as bad as many make it out to be. My factory bone stock Jeep is much quicker when I just let it shift itself in straight line accelerating (and I'm not bad with a stick shift). On the road course the auto stick works quite well. In fact, having taken my Jeep out on the road course several times, I probably prefer it to a manual trans in that kind of application.

In reality, It would be nice to have the option. That's where Europe has us beat, almost all performance sedans and SUV's are available with a manual transmisson. Unless a manufacturer comes up with a programer real quick, I don"t see the problem going away anytime soon.


It would be nice to have a programmer that could eliminate the rev limiter when in "manual" or at least up it to 7,000RPM (not that you'll ever go there), and shift much faster than it does now. Being that this is a newer electronic transmission, does anyone know what components are haydraulic and which are electric? Is the line pressure controlled electronically? Is there an accumolator? Are the shifts controlled via governor and line pressure? If it's all done electronically, what the hell is taking so long for the aftermarket to respond!!!!!

Red SRT-8, true enough, nothing ill intended. Are you an old school guy?

I'd prefer an auto gear shifter (specific shifter location for 1st,2nd,3rd,4th, & D) to the autostick. For me it's easier to know what gear I'm in and give better shift control around turns.

It also helps prevent the "oh sh!t, I forgot I'm in autostick mode" rev limiter embarrassment.:eek:

No problem here. I hope I didn't sound like my panties were in a bunch. Just friendly converstaion between Mopar fans as far as I was concerned. Yeah I'm an old school guy. My family builds a lot of mid 60s Mopars for a hobby/living.

I hear you about the option idea. As much as I like the autostick on the road course there is nothing to match the fun of driving a stick on the street. I love cruising around in my Ram just for that very reason. Although, hooking that truck up is a bit tricky.

The QC SRT-10s with auto transmissions are showing big gains in low end torque, firmer shifts and quicker ETs from reflashes that are available. Our Jeeps could definitely stand to benefit the same way.
