darksnake Posted July 7, 2011 Report Share Posted July 7, 2011 Has anyone used Royal Purple transmission fluid in thier '07-'10 GT500? I've used it in in my '05 GT with great success. But the GT500 transmission fluid specs call for Mercron V ATF, Royal Purple offers a Synchromax Manual Trans. Fluid and a ATF fluid. Was wonder what others have used and thier results.

inyadreems Posted July 7, 2011 Report Share Posted July 7, 2011 I swapped my tranny fluid to Amsoil Multi-Synthetic ATF and noticed a nice improvement in smoothness and engagement. Link to comment Share on other sites More sharing options...
1badshelby Posted July 7, 2011 Report Share Posted July 7, 2011 I swapped my tranny fluid to Amsoil Multi-Synthetic ATF and noticed a nice improvement in smoothness and engagement. I did the same. I feel it helped the 1-2 shift some. Link to comment Share on other sites More sharing options...
Ackman70 Posted July 7, 2011 Report Share Posted July 7, 2011 I'm running the Royal Purple and it does seem to shift better. Link to comment Share on other sites More sharing options...

vapor08GT500 Posted July 10, 2011 Report Share Posted July 10, 2011 I run the Royal Purple Synchromax in all the cars I have in and out in my shop, even track cars...great stuff!!! Alex Link to comment Share on other sites More sharing options...
darksnake Posted July 10, 2011 Author Report Share Posted July 10, 2011 Thanks for the positive input, as usual. Ordered my Royal Purple Syncomax Friday and it will be in my tranny next week. From past experience in GT's it also eliminates the increased notchiness realized with short throw shifters...smooooth shifting here we come :} Link to comment Share on other sites More sharing options...
bigsnake Posted July 11, 2011 Report Share Posted July 11, 2011 I swapped my tranny fluid to Amsoil Multi-Synthetic ATF and noticed a nice improvement in smoothness and engagement. I also did the Amsoil MS ATF and noticed a smoother shift. Link to comment Share on other sites More sharing options...
Freak Posted July 13, 2011 Report Share Posted July 13, 2011 I run the Royal Purple Synchromax in all the cars I have in and out in my shop, even track cars...great stuff!!! Alex As a big fan of RP, I'd love to use this stuff, but I don't want to jeopardize the warranty, especially considering the transmissions seem to be the trouble spot in these things. Do you know if the Syncromax is warranty friendly? What about using the Max-ATF? Or is that a bad idea? Link to comment Share on other sites More sharing options...

wingsnut Posted July 13, 2011 Report Share Posted July 13, 2011 RP for me just yesterday. Noticed right away it was a lot smoother on the 1-2 shift, but, I just installed a new MGW shifter a few days ago and I made some adjustments to it at the same time I changed the tranny fluid so I am not 100% sure if it was the new fluid or the adjustment to the shifter that made the difference. Either way it is a ton better than it was. Link to comment Share on other sites More sharing options...
SSGT500 Posted July 20, 2011 Report Share Posted July 20, 2011 I recently installed Mobil 1 full synthetic at the advice of a Tremec factory tech. I works better than anything I tried before including Mercon V, Castrol ATF or Pennzoil SyncroMesh. Link to comment Share on other sites More sharing options...

SSGT500 Posted February 14, 2012 Report Share Posted February 14, 2012 About 3-1/2 quarts. The manual says 3.65. If you go too full, it will spit when you run the car hard. http://iihs.net/fsm/?dir=294&viewfile=SPECIFICATIONS.pdf Link to comment Share on other sites More sharing options...
E.Marquez Posted February 14, 2012 Report Share Posted February 14, 2012 I've been using RP Synchromax in my S197 for 2 years now, and felt the difference after the swap, smother shifts in all gears. Already purchased 4QT for the GT500 to be installed when I get home along with a new clutch and flywheel.. Assuming it works as well in the TR-6060 as it does in the TR-3650, and I see no reason it would not.. I’ll be a happy camper. Link to comment Share on other sites More sharing options...

But the GT500 transmission fluid specs call for Mercron V ATF, I could'a SWORE my 2010 GT500 calls for Dexron II. I *thought* it said it in black letters on the side of the Trans. Now I'm gonna have to check. Phill Link to comment Share on other sites More sharing options...
54First Posted February 20, 2012 Report Share Posted February 20, 2012 Phill, My 2008 owners manual calls for Mercon, IV i think, but the Dexron sticker you think you saw on the trans is really there. Steve Link to comment Share on other sites More sharing options...

Steve Oh crap. I better check my owners manual. Not that warranty is a concern, that went out the window with the first few mods. I was under the impression that I could run a Dex. II syn substitute. I'm about to pull the rear axle down to install a set of Shelby/Baer rear Extremes and I was planning on changing the trans and diff gear lube to Royal Purple Syn. when I did. Can we run Royal Purple (or any other good Syn.) gear lube without harming the carbon fiber syncro rings? I believe the Mercon IV is comparable to the old F-type ATF, which had abrasives in it for the Ford A/T's so I ASSUME FoMoCo wants a similar type ATF in the trans. I know.......ASS-U-ME !

Gerry Chase 1128 Posted June 1, 2012 Report Share Posted June 1, 2012 At 40k miles, I changed out the factory transmission fluid with Royal Purple Synchromax. Have put about 400 miles on since with some stop and go city traffic and it is noticeably better. 5th gear used to have regular but slight gear rattle, and now it is completely gone. The specs call for 3.65 quarts, so for the .65 quart I measured the quart container from the bottom to where the fluid level is at the top. It is six inches. 2/3 of six inches (.65 approx.) would be two inches from the bottom of the container. Marked the location between the labels, put a light behind the container and watched the fluid level drop to the mark as it was pumped into the transmission.

Chris410 Posted August 15, 2012 Report Share Posted August 15, 2012 What is the recommend interval when it comes to changing the transmission fluids? I bought a 2010 GT500 a few months ago and I am not 100% sure if they changed the fluids or not (I'm highly doubtful they did) my car only has 10K miles however, I am curious about what intervals everyone recommends. I will stick to the OEM fluid until my warranty is out, I am sure everyone is familiar with the issues the TR6060 has with the 1st to 2nd gear issue so I do not want to risk any potential issues should I run into problems. Thank you in advance! Link to comment Share on other sites More sharing options...
