I have a TO 2011 R/T 6speed, I have had it for about 3 weeks and have 800 miles on it so far. When I drive normal, my 1 to 2 shift seems notchy but shifts fine. the other gears seem smooth. But when I get on it, the 1 to 2 shift seems to grind before going into gear. its not like I dont know how to drive a manual tranny, been driving them since '85. Now I have heard about the skip shift thing, but I dont think it applys in this case since I am going WOT, also I havent encountered the skip shift when driving normal, I dont think its on the 2011 models. So long story short, does anyone else have this issue, is it perhaps linkage that isnt set up right or what. Its getting irritating to say the least.

The notchy 1>2 shifts are common to the Tremec TR6060.

Give it some more miles, as the internals will break in and it will get smoother. This is more pronounced on cold driving, and gets smoother after a few shifts and the oil in the transmission warms up.

There were changes (assymetric synchros) made to the 2010s to reduce shift effort (1>2) and reduce the gear "nibble" as Tremec describes it. The tolerances in these transmissions are tight - so much that ATF is the lubricant used.

I noticed the shift quality improved by the time I had 3K on my 2009, but the notchy cold start up shifts are there, but after 3 to 4 shifts, it smooths out.

I hope it does improve , perhaps I should chill out for awhile.

You are not alone, I have the exact same problem, even after letting the engine get to temp it still wants to go down the road awhile before you can really work through the gears like a pro.... I am hoping the parts will wear in and it will go away... It has gotten better, it was really bad for the first 1k, I'm now at 3k.

PS mine is a 6 speed 11 RT classic.

Our 2009 six speed is still very notchy from 1st to 2nd at about 6,000 miles, but all is acceptable after a few miles of driving.

I had the same issue. Changed the fluid @ 1k miles to Amsoil Synthetic Multi-Vehicle Automatic Transmission Fluid. It made a noticeable difference. I was suprised to see how dirty the factory fluid was that soon. It was red with a nice gray tinge to it.

 

[Blackout]

Mine cleared up, and now at 20, 000 miles all is smooth!

Thanks for the suggestion, is it recommended to use an auto trans fluid in the manual trans case or do they have a different formulation for that application?

 

[VelocityBoy]

My '09 Tremec is still very notchy after 17K miles. PITA at the track because that's the one gear I keep missing.

 

[bamill88]

I experience the same notchy shift 1-2 on my 2011 R/T 6 speed. Just hit 2k, we'll see if it clears up someday soon.

 

[Bryan]

My 2-3 is bad, but the 1-2 is way worse, sometimes it takes 2 notches to get it into gear it feels like.

Mine too never has done the 1-4 shift.

Before i purchased this car, i wondered why everyone was putting Hurst shifters into their cars... Guess i know why now, at least its a positive shift with the new shifter, the stock one is very soft.

Dave,
How many quarts did it take?
and
Did you do it yourself?

Yes, ATF is whats recommended. Anything else may void the warranty. This is what I used. AMSOIL Synthetic Automatic and Manual Transmission Fluid

3.25 qts is what it took to fill it approx 1/2" below the fill opening. Theres very little room between the fill opening and trans tunnel so you'll need one of thoes inexpensive pumps to get it back in. I also removed the rear x-mbr as it makes it easier to drain without getting fluid allover. You will need to support the back of the trans if remove the x-mbr. I have a lift so it was easy to do. If you DIY be carefull when you remove the drain plug, the hot fluid comes out of that 9/16 hole like water outta firehose.

Amsoil makes some of the best lubricants on earth, but it did nothing to improve the cold shift problems on our SRT 6-spd.

Mike- I tend to agree with you to a certain extent. I noticed the notchy feel along with a slight nibble when I first got the car. I dont think the cold weather notchy feel will ever go away. When the trans gets up to temp the notchy feel goes away but a slight nibble was still there. After the fluid change @ 1K miles I did notice a change, it still had a slight notchiness when it was dead cold during the winter months but helped the nibble a lot when cold.


I don't know if it's the added mileage/break in on the trans or the fluid change or combination of both but mine is very smooth now when it's up to temps. Maybe the factory fill is a slightly higher viscosity.:dunno:


I'm in Florida and don't experience the sub zero temps like the northern folks do. Some days the fluids are up to temp before you even start the car :icon_lol: It's kinda like exhaust drone....... some have it, some don't with the exact same exhaust.

Kind of funny you should mention this. When I did my second service on my Harley at 5k miles I put In Amsoil in all the holes. Prior to this I always noticed a chattering in the clutch during takeoff. After the oil was replaced no more chatter, it as smooth as silk and totally changed how the clutch behaved. As much as wish I could buy this fluid/oil in a store we will have to deal with the dealers. I'm an Amsoil believer..

1-4 skipshift is there, I actually had to change my driving style to confirm that it was still present though, if you accelerate easy (less than 25% throttle) in first up to 20MPH it will pop up 1-4 on the EVIC, this never happens to me in normal conditionals as I normally shift out of 1st around 1800-2000RPM which is less than 20MPH...

I have a 2010 SRT and my trans is notchy. I was thinking for a brand new car, high dollar car...this was horrible. My car only had 24 miles on it when I bought it...so not many miles for people to have test driven it. I test drove a 2011 SRT yesterday and it shifted much better than mine. So, I was thinking about taking mine in for service now. At first I was thinking that it needed an adjustment or something...but its a hydraulic clutch. I willing buying the Hurst soon and thought I'd better take it in before installing because the dealer may say that's the cause. At the same time, I feel like it would be a waste of time and that I should just install the Hurst and hope that it fixes the issue. My car only has 2500 miles on it now.

Any suggestions?

 

[Apro4x4]

Yes I concur...give it some time and a fluid change.

BTW: get the skip shift eliminator.
