If it makes even 1/2 the difference there as it did in the FR-S, I'll be grinning from ear to ear (won't hold my breath though...the Tremec T5 transmission is a steaming pile of poo).

Hey thanks. glad you enjoyed my research!

if your t5 calls for an ATF dont use the pentosin MTF2 in there
if you need dex3 and mercV compliance they have a pentosin ATF1, but I dont know that tranny, not the same as my borgt5

I have yet to send my sample in for uoa, but will, having tracked it heavily
as for fill volume, you fill till it drizzles out the hole guys

Gem, I appreciate your concern regarding the Mustang trans. It does call for Mercon V, and is similar to the BW T-5. I've driven many BW T-5s, and though not a real nice transmission, they feel great compared to the Tremec version in this car. My problem is not with cold shifting like in the FR-S. It gets worse as things warm up. This leads me to believe a slightly thicker oil will help. Many people with this trans have reported good results when switching to RP synchromax/GM synchromesh/Redline MTL (70W80)/etc. I've tried Amsoil's thinner (don't remember the name) MTF, the RP synchromax, and Amsoil's Torque Drive ATF (very robust for an ATF). All felt better than the OE fill.
I already have the fluid in the trans, so I'll give it a try and see how it goes. If the worst happens, there is an adaptor plate available to swap in a TR-3650 5 speed or BW T-56 6 speed trans. Either one would be a vast improvement over what I have now.

drain out the pentosin from your mustang, save it for the 86, ok to reuse, if its not dirty

refill with one of these

lmk, think you will like the torco in your Mustang! I'm a bit of a fluid geek, so if you try it PLEASE let me know

Awesome. I was just going to ask about track use. I've got the MTF2 going in later this week, along with my first track day of the year Saturday.

Looking forward to your UOA results, as well as my first Pentosin-aided gear change. Thanks.

I've heard good things about Torco. Importing oils into Canada can be a pain in the arse, so I'll have to see if I can find a local supplier. I like how it stacks up...

....................Amsoil Torque Drive ATF...................Torco Hi Vis.......................Pentosin MTF2

K.V. @ 100 ..............7.4................................. .........8.32...................................7. 7
@ 40.......................37.1..................... ...................35.0........................... ........38.3
V.I. ........................170....................... ..................216............................. .......177

I couldn't get the numbers for the Pentosin ATF (password protected), but I like the looks of the Torco. Amsoil also listed PPM for boron, calcium, and phosphorous at 133, 28, and 230 respectively. Of the fluids I've tried so far, I like the Torque Drive best. I'm not an oil geek yet, but I'm working on it.

I'll stop polluting your thread with Mustang crap and shoot you a PM if I get my hands on some of the Torco ATF. Thanks for the suggestion.

The Redline oil with closer specs to the Pentosin MTF2 is
the Redline MTL - 70W-80

penn synch * pentomtl 7580 * Redline MTL * RedLIne MT85

KV @100 * 9.08 * 7.7 * 10.6 * 12.0
KV @ 40 * 41.6 * 38.3 * 56.2 * 64.3
VI * 208 * 177 * 183 * 172

the correct kinematic viscosity of a 85 weight oil is somewhere between 7 and 14

SAE service level defines targets for a 75W gear oil to be= 4.1@ 100F and 7.0 based on that and the fact that folks using MT90 and folks using syncromesh by pennzoil are reporting better than MTL results

there is a rumor that the GM syncromesh IS pentosin, but I dunno

this led me to believe the MTL90 some guys on this forum may be my second choice so I did a little experiment that cost me $60

I dont put pennzoil in any of my cars

here is a list of their salient characteristics

penn synch * pentomtl 7580 * mtl90 7590 * smx-s

KV @100 * 9.08 * 7.7 * 15.6 * 11.9
KV @ 40 * 41.6 * 38.3 * 90 * 64.4
VI * 208 * 177 * 185 * 183

I dunno the weight of the syncromesh, and the smx is a 75w85
I had hoped better for the smx and the redline but they too are thick when cold

FAIL

SAE service level defines target KV for 75W gear oil to be= 4.1@ 100F and 7.0 based on that and the fact that folks using MT90 and folks using syncromesh by pennzoil are reporting better MTL results

Pentosin is the lightest of oils, of the four above

I use their line up of oils in Porsche audi and BMW products in my garage

Its great to put something fresh in there, even better to know why it worked better, and less of a dice roll if you really know whats different about them.


I also considered http://www.redlineoil.com/product.aspx?pid=140&pcid=7
its thick but not as thick as the MT-90, this one is specifically to address the cold synchro symptoms
BUT its a bit thick ish, and performs alot like the MT-90, but it MAY be an improvement

if you were banned as Gmooker? isn't it technically against the rules to make another account with another name?

technically thats pretty far off topic, but I will offer you my reply:

I'm allowed to be here till someone says I am not.

so long as I dont cause drama, I have expressed to the admins my desire to be a member of the community and add value knowing fully well my viewpoints arent always popular. take this thread where i may say I suggest a oil you can try if you like, and yet so many come at me like I'm ill intended. I'm not. Same with another thread where I a new vendor just rubs me the wrong way. Its for the community to know they have never sold a part ever before, and have only made one prototype of two LCAs, and so its never been tested-while I have a hard time supporting that sort of thing, Now a days, I must simply step out from a thread before I get drawn into a tennis match. Trying to be a bit better about my making comparisons and blanket statements, but we all do it so its taking a position and trying to not upset the moderators again, its my nature to ask for clarity, question, challenge and define. Not everyone likes it, but its the nature of science.

why, you got something we need to talk about? I'm here to talk if you need to.

@Huehuecoyotl

I was just curious is all. cause I see Gmookher was banned, and you are clearly advertising that you were Gmookher

[Huehuecoyotl]

My love for the platform is strong as evidenced by owning two 86, one fully on modded with alot of tested ,proven, mods that I openly share as much as I can about, and also by my passion for cars and all things with wheels in general.

We are all human, so I dont expect everyone to agree with everything I say, but I truly DO hope I can add value to the forum for owners and ultimately make owning, and improving and finally driving your 86 as joyous and experience as my wife and I have been enjoying our twins. I'm here for the community, not the vendors, and am here to build my car and share my build with everyone. I love seeing other well built efforts as well.
I'm not advertising, I'm the same guy, same car same tester, Just trying to be more sensitive this round and will make every effort to avoid it getting UGLY.

Put this in last week. Temps are around 60 degrees here but the shifts seem to be a lot smoother. Noticed more so when the car was cold.

[Chimpo]

Finally got this stuff in yesterday. Quick spin: YES!

[Staf00]

Is this the same Pentosin MTF2 that I think it is? A 5 pack for that price is giving me doubts...otherwise I'll just pick it up locally for ~$20/bottle.
