Was a bit better at Daytona. I would say less. "Difference" in shifting between cold - warm - hot... More consistent...

I have been running the Tremec fluid for a year now. Since the swap...I have run the FIRM, VIR, Sebring, Roebling and PBIR. Shift has maintained a smooth feel. I haven't noticed any issues with 2-3 shifts when cold or hot. Also run a significant number of AutoX events (including ProSolo) since the swap. I'll be changing fluid again (with Tremec) in April.

One thing that caught my eye is how much higher the viscosity is. It is truly not similar to the ATF that is recommended by manual. Have u had 2-3 shift problems on track before. And if so would you say it was immediately remedied by Tremec mtf?

Agree, the Tremec fluid is definitely a higher viscosity than the OEM and other numerous ATF fluids that forum members like to run. So why then is the Tremec fluid an acceptable choice if Tremec's own tech data sheet for the TR6060 recommends ATF fluid?
Tried to call Tremec a few weeks ago to ask them this, but nobody was answering the phone during normal business hours. |

IMHO, you are caught between GM and Tremec. GM sources the units from Tremec, but doesn't want to use Tremec specific fluid. GM wants a common fluid that is easier to store, ship, and train techs on. So, Tremec says Dexron is an acceptable fluid in the -6060. If there is a warranty issue, it's GM replacing it, not Tremec. If you purchase a transmission (ANY transmission) from Tremec, they want you to use the HP-MTF. In fact...the 1st line in the product description is: High quality transmission fluid suitable for use in any TREMEC transmission. https://www.tremec-store.com/collect...smission-fluid https://www.tremec.com/menu/manual-transmission-fluid/ For reference...the TR-6060 is the OEM designation for the Tremec Magnum. The reference for the Magnum says use HP-MTF. Personally, I believe my car sees moderate usage. I put on few street miles, but I do AutoX/HPDE frequently. One of my routines is a regular change of all fluids/consumables. I change my diff every six months, and the transmission fluid once a year. I haven't done any research into the longevity of the HP-MTF vs Dexron, because I cycle through it quickly. That may be a consideration if you plan on using GM's service interval.

Tremec rep kept defaulting to gm rec and said they did all their nvh and track testing with atf etc. but I am worried i'm going to overrev my car into 1st on track with these terrible shift lockouts so trying something new. One thing also confusing me is the GM synchromesh manual fluid is much closer weight to this tremec stuff not sure i've seen anyone on here run that but they do on c7 forum. viscosity is similar. Wondering if this provides the better shifting at higher rpms i need with warranty friendly fluid. Can't see tremec fluid causing malfunciton in my trans so going to try it for a bit. Those of you running it - have you guys been filling it up to the brim of fill plug or taking 8oz. Tremec rep I spoke to again defaulted to GM rec but said expansion properties are differrent. Lot of confusion...

I've been using Mobil1 ATF and 2-3 shifts are much better. Last event was 3 days long and only had 1 hiccup. I change it almost as much as the oil.

Did you have the 2-3 high rpm lockout issue before you changed? I'm wondering if there is any difference between my redline D4 atf in car now and mobil 1. Wanted to totally shift to mtf but if it solved the same issue for you since I know you track a lot...

The OEM stuff was very bad including doing the 2-3. Redline D4 was making it nice and smooth but was still having some 2-3 issues. So far fewer issues with Mobil1 on track.

Might order mobil1 to test as well after tremec mf And Matthew: are you filling tremec all the way up to fill plug/till it comes out or taking out 8oz from max capacity?

BTW - I was also really unhappy with Redline D4. It’s one of the reasons I went to Tremec for an alternative.

Were your problems mostly around high rpm 1-2 2-3 shifts with D4? I have been actively avoiding 2nd gear in low speed corners because NLS 2-3 has been on the verge of catastrophe at recent track events Thanks for your input on this
