Grinding into 1st gear 2017 GTS

[CerBlue17]

From a roll or down shift into 1st. Will grind and can't get into 1st or slight grind and goes into gear on second try... It's as if clutch not pushed in far enough. Doesn't happen all times put appears to be happening more often. From a complete stop goes into 1st fairly smoothly. Hard pulls 1st thru 4th are fine although a little "notchie" which i believe is normal for this transmission? Car not tracked or abused and was broken in with care.

I dont believe 1st has a synchro...

[Voice of Reason]

In 2 different Gen Vs across 25k miles ive never had a grind going into 1st at any speed. Ever. Sounds like you need some warranty work.

[Track Pack]

I have owned two Gen 5s and never had that problem either...???

[sadil]

Never had this problem. I only grind when I get really lazy with shifts.

[ViperPete]

My car grinds consistently into reverse if I don't go into a forward gear first.
No problems with any forward gears though.

[swexlin]

I have no issues with any gear (knock wood), including reverse.

Pete, I would have that reverse issue looked at.

[CerBlue17]

Definitely have issue...not from lazy shifting..wish I had idea what's going on before bring to dealer.

Man, these Gen V issues are freaking me out. My Gen II GTS and RT/10 were pretty rock solid.

Although it's not a "common" problem, the syncros in our TR6060 transmissions are weak. I had the transmission replaced in my old TA and carbon car. Both were 2014s and built around the same time (coincidence?). The ACR I just purchased has 4k miles on it and although I haven't shifted hard through the gears yet, the car shifts buttery smooth.

I have when i first bought the car. The Viper tech said that reverse isn't synchronized and that is a common thing. My T56 in my SRT10 doesn't do that....

Mine usually does the same, I will normally shift into 5th before going into reverse and no grinding. But if I try to go to reverse straight away I will usually get the grind.

Bullshit...reverse is synchronized, as are all the other gears. It shouldn't grind going into any gear, period.

I have a related question..... My brand new 2017 ACR Extreme has a very different feel shifting into 1st gear from a start than my 2008 does. My 2008 doesn't require much gas at all when starting in 1st gear from 0 mph, but it seems that my ACR needs quite a bit more gas to get it moving or I literally stall. Has anyone else experienced something similar to this, is there something weird going on with my car, or is there a legit difference between the Gen IV & V Vipers with their transmissions? Thanks!

[swexlin]

It's the lighter flywheel/clutch in the Gen 5. I almost never stalled my Gen 3. My Gen 5 I stalled twice in 2 miles the first drive I ever took it on, and I still ocassionally do!

[CerBlue17]

Ok..took car out for ride..1,700 miles, 2017 GTS
- From start up into 1st smooth no problem.
-Upshift through all gears was smooth at all speeds no problem
- downshift through 2nd smooth no problem
**-here's the problem- downshift into 1st from 2nd grind and won't engage UNLESS I TRY AGAIN OR COME TO A COMPLETE STOP than it goes into 1st no problem.
_only started happening in last 50 miles.

Synchro? If so, which one?
Slave cylinder(hydrolic)?

Called local dodge dealer left 3 messages for service manager..no call back.

You want another one or you wouldn't still be hanging out with us.

[flyboy1of1]

I agree with SWEXLIN, I've stalled mine a few times -at first I thought I was starting out in 3rd. " Live & Learn" Thanks Bob

[7TH_SIGN]

You want another one or you wouldn't still be hanging out with us.

I usually stop by and answer any question in my PM box. Always willing to help others. Wouldn't mind an ACR

The Viper truly is a special one of a kind machine.

Another vote - reverse is synchronized, it should never grind if the synchro's are not worn.

One thing that has not been mentioned, once you shift, remove your hand so there is no preload on the shifter, this wears the synchro's. In effect, do not cruise with your hand on the shifter.

There is a lot of 6060 bashing in this thread, the trans is not always the issue. If your clutch does not quickly and fully release, the synchro's fight their way thru the shift. For information sake, the typical G5 oem clutch appears to release fairly high, however, it does not fully disengage until one or two inches from the floor. That means if your shift is not totally perfect (foot at the floor), you are wearing the synchro's on each shift.

I will see if John Donoto can add to this thread and break down the pros/cons for the 6060.

[CerBlue17]

My question is:
-why does it shift perfectly from 1st to 2nd, but not 2nd to 1st?....unless car completely stopped then no problem going from 2nd to 1st.

[Bill Pemberton]

Frankly the Synchros were upgraded a long time ago and there are very, very few issues with the T6060. Used in Vettes, Hellcats, and more , and definitely heavy duty synchos in first and second --if I remember correctly they are triple cone. Would suggest you get to the closest Dealership , as this is unusual and frankly when one hears about something like this it is usually in the late Fall or Early Winter where someone is trying to force into first when the car is cold and tranny is not warm --common concern regardless of transmission. We hear more problems at our Ford Store during this time of year with the MT-82 ( not anywhere near the solid transmission Tremec makes) as it really needs things warmed up before shifting quickly or even going into first through second.

Good luck , but regardless of the car, if it is cool out , good idea to wait till the tranny is up to temp before shifting quickly.

[swexlin]

Excellent post Bill, thank you.

[CerBlue17]

Thanks Bill. Have appt. with dealership on 12th soonest they can take me. Never tried to jam into gear. Problem regardless of temp..again, only when downshifting into 1st when car is rolling....once car is stopped it down shifts into 1st smoothly....1st to 2nd is also fine. Just looking for opinions as to what may be causing problem since local dealer service manager cant seem to find the office phone to return my calls.
