Tremec TR6060 1LE ISSUES!

[markgws6]

Mine will be notchy still after the engine is warm and i've been driving for about 5-10 mins. It does not get very cold here except for in the mornings. And I always warm my car up for 5 minutes before leaving for work or coming home.

This is an ongoing issue and in my opinion based on the amazing number of us struggling with this issue on all major supplier's. Ford, GM, Chrysler cars equipped with the TR6060 transmissions.

Please share if anyone is struggling or will be soon struggling with similar notching issues or grinding issues with 1>2 shifts and/or 2>3 shifts.

Background:
1) I have been driving manual cars for 10 plus years with no issues at all (mustang, GTI, etc.).
2) This is NOT and Nor does it have anything to do with the 1 to 4 skip shift that this car (or transmission) has. I have had it come on several times and no issues with that.

Problem:
My car is a 1ss 1le with 340 miles on it. It started from day one with 12 miles on it where it would will feel notchy from 1>2, 2>3 when shifting. This occurs every time to some degree from 1>2 and about 50% of the time from 2>3(with a hot engine and transmission it is slightly reduced).

Another BIG problem is when down shifting or up shifting from any gear to 2nd it physically will not go into 2nd. I can try to rev match with the clutch all the way in with no luck. Finally, at about 15 mph or so and about 15 lbs of forcing it back into 2nd it will clunk into gear with a notchy feeling

PLEASE ALL OF THE 1LE GUYS SHARE YOUR SHIFTER FEEL GOOD OR BAD SO I KNOW I AM NOT ALONE GETTING THE ONLY BAD 1LE TPW OF 10/15.

I am not complaining just trying to get feedback and will share my story as it progresses. Dealer apt. next Tuesday.

I am sorry to hear of your problems....I am happy to report I don't have them...

I drive the car all year round - and up here, that means sub-zero temperatures at times. Even then, while slightly notchy, I have no problems shifting between all gears. As soon as the coolant is up to temperature, it seems as though the transmission smooths out to silk shortly thereafter.

BLKSS1LE, what ever happened to your dealings with Chevy?

I think that's the key, fluids up to temp including the trans. Easy if you have the extra gages, I just take it easy until the trans and oil temp are up before aggressive maneuvers.

Getting the trans up to operating temp helps a lot with the notchiness, but my trans still liked to grab and grind. I highly recommend the Ideal Garage Master Cylinder, as this got rid of almost all of the notchiness and grabbing, especially when cold. However, I still have a problem with the 2nd to 3rd gear upshift grinding hard at 6,000+ RPMs. I know most people don't do this all the time, but seeing as my car lives mostly on the road course, I've done this shift hundreds, if not thousands of times. I'd say around 1 out of 5 times it happens with no rhyme or reason as to why (if you tell me it's user error I'll slap you).

The dealer told me it's normal, and to be honest, I don't necessarily disagree. I've spoken to other 1LE owners at the track and I'm not the only one with this problem either. I spoke with Rockland Standard Gear and they guaranteed me that if they rebuilt the trans with carbon synchros, the problem will go away because they've seen it before.

I've fought with dealers and regional service managers before, and I'll never go down that road again, so once the 2nd-3rd synchro gets blown to pieces, I'll take the trans to Rockland Standard and get it built the right way.

Boss 302 owners are having the same problems with their Aisin transmissions. Gears grinding, etc. but most of the issues seem to come from guys who do alot of track time.

If only the 1LE Camaro and boss 302 were designed and marketed for track use...

I actually think Chevy did a good job with our cars, and if they fixed every little problem that could be caused by excessive track use, you'd have a much more expensive car... Wait, they did. It's called a Z28 and I can't afford it. So I'll live with the occasional grind and upgrade it when it wears out.

Amsoil multi-vehicle ATF or RP Syncromax help mine out alot...and like you guys said, >180F tranny temp helps immensely although I still have 1st and reverse intermittent issues. It always amazes me whenever I drive the wife's Scion FR-S how buttery smooth that transmission is in comparison. I know, it's not apples-to-apples, and I've certainly beat on the Tremec alot in 4 years, but the difference is night-and-day :(

Totally agree! As for the FR-S or any other 4 cylinder, its easy to make a smooth shifting transmission for a 200hp car that also has the appropriate torque. 426hp is a totally different game.

The transmissions in the FRS aren't that great either. The one in mine was cold blooded as could be. I had to let the car warm up just to be able to get it into reverse to back it out of my garage. Many people on the FRS forum have voiced issues with their trannys.

[ducatisl]

I know the FRS has it's problems, some serious ones too, and is a COMPLETELY different animal: I was just stating how differently, in a good way, it shifts in comparison to the Tremec in our Camaros. This is one of the few times I agree with that horridly anti-American Jeremy Clarkson when he drove the ZR1 a few years back in Top Gear and trashed the Tremec in that car as well. Surely Top Gear has had some cars on the show with at least 426 hp and manual tranny's they liked?

I don't hate the Tremec, and I'm certainly nostalgic, and appreciative for them bringing decent manuals to the market starting with the old Fox body T-5's. However, I'd probably switch to a 4L80 if it didn't add another 100 lbs, but my particular Tremec shifts precisely when warmed up (6800-6900 rpm when raced, no problems) and the ACT clutch, while looking very abused during a recent motor swap, still works as it did new 3 years ago.

They do, but generally those cars cost alot more money than a Camaro 1LE.

[markgws6]

I find it amusing and funny that in so many years of R&D and engineering research, they cannot make of find a high performance tranny that shifts smoothly, even for 400+HP cars. I drove a Viper maybe 5 years ago and I remembered it shifted smooth at low speed but I did not get to drive it fast. I had a 68 GTO 350HP with a Muncie M21 in it and it shifted almost exactly the same as my 2013 (and that car had probably 300K miles on the tranny or more.) Did we never learn anything in all of those years??
