Ok, wha't have "you" had the best luck with as far as manual transmision fluid goes?

I'll second the GM Synchromesh fluid, with a bit of Ford friction modifier thrown in for good measure.

well decided on AMSoil synthetic ATF. I talked with them and they seem to beleive it will work fine. The guy at the tranny shop said that the AMSoil would be a good choice also.Also one of the guys at work is a "perfered customer" and gets a discount.
I do intend on leaving it short about 4 ounces until I decide it it needs friction modifier.
I'll try to update when the motor and tranny are back in.

I used Mobil 1 in the T5s I have ran, I have shattered the input shaft in one, bent the shift pivot mechanism in another and neglected to check the fluid in another until it stopped being nice to me. None of the three had failures resulting from a bad lubricant just a bad owner :D .

I use Redline D4 Synthetic ATF with no friction modifier. No problems to report.

I just recently changed over my shifter to a B&M Ripper, and also changed the fluid while I was at it, like Duffy I also used the Redline D4 Synthentic with no friction modifier, 1 week in no problems, so I would second duffys choice as well. Mike

Mobile 1 5W/30 motor oil with friction modifier.
Shifts Smooth, big improvement over standard ATF. :)

"I use Redline D4 Synthetic ATF with no friction modifier. No problems to report."

Me too! My transmission would not go into 1st without hitting another gear, before the fluid change. Afterwards it shifted 100% better and would shift to 1st even after it was hot.

I recently used the GM syncromesh spec under the Penzoil brand, and 4 oz frictoin modifier.

My 2nd gear syncrho is starting to wear and the change of fluid made it shift significantly better, and its quieter when it does grind. I am not sure if this is due so much to the type of fluid as it is to the fact that it is new fluid.

The only possible negative I have noticed is it becomes noticeably harder to shift at lower temperatures, such as upper 50s. I don't think I would have had this problem with the Mobil 1 synthetic ATF.

Where might one be able to purchase this 'redline' transmission fluid?

I also use Synchromesh with a bit of friction modifier. And, I also noticed that it is harder to shift in cooler temperature, until it warms up a bit.

Syncromesh is a bit thick when cold. But offers better protection and feel when the fluid is HOT. And thats when it matters. :D

AMSOIL ATF.
What ever you do... do not put 90 weight in it.
These transmissions were designed for ATF which was the preferred fluid before the development of Manual Transmission Fluid which is used in more modern manual transmissions. A lot of guys have started using the Manual Transmission Fluids.

The AMSOIL ATF does not need a friction modifier added.

I have also read here that several guys have added friction modifiers to the manual transmission fluid. You may be upsetting the chemical design of that fluid. Just because you think it is working fine, unless you are chemical engineer you do not really know if you are doing any damage to the transmission or not.

Pennzoil syncromesh, same as GM at half the cost.

But it says Pennzoil... I avoid things in Yellow and Green bottles like they have an STD that I can get by just touching them...

With that said, I went with GM Syncromesh and some Ford friction modifier. And yes, I am made of money.

I won't touch pennzoil motor oil, you shouldn't need modifier with syncromesh it already has it.

I am really curious about the need to add a friction modifier to the syncromesh fluid or ATF which I have seen mentioned in this thread.

All the friction modifiers I have seen from Ford or GM have sulphur (rotten egg smell) in them which is an extreme pressure additive for hypoid gears (differentials). I don't think the SC 5 speeds have hypoid gears in them which is why Ford put ATF in them.

There are several different friction modifiers available to oil manufactures. so does Ford and or GM now have a different friction modifier that does not have sulphur in it that I might not be aware of?

I am not sure. I had like 50 pages of posts printed out an in my binder in the garage (this was back before I had like 5 extra laptops and computers sitting around) related to it, and it seemed that more often than not the modifier was being added to the Synchromesh. So like the sheep that I am I just followed along.

Alan Same here, but mostly thats all i could find at the parts stores. 4oz of FM with carbon fiber synchro rings and shifts great in all temps. :cool:

4oz of FM with carbon fiber synchro rings

This may be the key thing there. I seem to recall reading somewhere about the FM being used in the fiber rings and not the brass ones..

ricardoa1

GM sell both syncromesh with or without. If you have brass rings you dont need any FMod.

If you buy the syncromesh from the parts stores in the QS or Penn bottles it does not have any FMod so you need to add it.

FMod gets absorbed by the fibers and increases it friction so it slows down parts faster allowing you to shift into the gear faster/better.

ATF is thinner then the syncromesh so if you live in alaska then you will have a hardtime in the morning with the syncromesh. Just let the car warm up and shift easy until the fluid is warm, then rip all you want.

I've run the Pennzoil Synchromesh and was not happy with it. I was having to replace the 3rd gear blocker every year. I've switched to Valvoline High Mileage ATF with an extra bottle of Ford friction modifier. I've gone 2 years now without a rebuild and am only swapping the tranny out to check the condition of the internals. Remember now, all this car does is run the 1/4 mi and drive back and forth to the dragstrip.

i too did not like the synchromesh i now run regular mercon 5 in it and it shifts the best it ever has

Ok sounds like gm syncro for alot of guys, looks like about 12 bucks a jug, how many will i need? capacity?

The Manual says around 3 litres. I just filled mine and it took slightly less than 3 though I also used a small bottle of friction modifier so the 3 is bang on.

Thanks Sean. Now all i have to do is figure out litre/ to quarts. LMAO. Did you use syncro mesh also?

I went with GM Syncromesh $10.00 per litre at the local GM dealer and the ford friction modifier as per Fast Ed, Ricardoa1, and DLF, all of whom have much more experience than I.

1 litre = 1.05 qts

The last time I had the 5speed fluid changed they put in Mercon 5 per the manufactures recommendations. I don't know if they put in the friction modifier or not. Mercon 5 is synthetic oil and I don't know if it has it already. Maybe it is listed in some obscure area but, I have an actual Ford 1995 Thunderbird repair manual and for the life of me I don't see any mention of the friction modifier, just Synthetic Mercon E6AZ 19582-B. How did this Friction Modifier come about?

i use d3m there was 80w90 when i bough the car so i used d3m and changed it often to wash the trans and it shift a lot better!

Here it is 2012 and I haven't changed the tranny oil.
Oopsy, Still running the same 5w/30 Synthetic motor oil and still no trouble.
It looks as good as the day I put it in... 2004 :p

Kind of an old thread but would like some more input on this subject. Just getting ready to put fluid in my 75000 mile M5R2 and still unsure about what to use. Leaning towards the Valvoline High Mileage tranny fluid with a bottle of FM added. I am not a big fan of Pennzoil products.

Anyone with more input would be greatly appreciated.

Mike Puckett
08-06-2012, 02:27 PM
That's what I use in mine. I don't care for Pennzoil stuff either. I've tried several types of fluids over the years and finally switched to the Valvoline High Mileage with the friction modifier in it. I haven't noticed that any of the fluids worked any better than the ATF does and will probably stick with this stuff from now on. I didn't get any better wear on the blockers with any of the other types of fluids. Only problem I've found is that the friction modifier stinks and the smell lingers for awhile if you spill it.

I was going to change my trans fluid the AMSOIL manual trans fluid but after talking with one of the senior tech service guys at AMSOIL, he told me that running a manual trans fluid in a manual trans that calls for an ATF will increase operating temps of the trans/oil which makes since. Higher temp is caused by friction of the thicker oil that the trans was not designed to use. I have decided to stay with the ATF. Also the lighter the oil the more power you have over thicker oil. Which also relates to fuel economy too if your interested in that.

I asked Tech services about the Super shift and they said no just stick with the ATF.
If you have an SC that you use only for drag racing and trailer it to an from the tack then you can use the MTF ( Manual Transmission Fluid) because the you will not be running the car long enough for the trans fluid to get Hotter than ATF will.

Ive tried atf and frankly there has to be a better option and I wont run atf or synchromesh in the trans im building. If you could Ralph ask them what the comparitive weight 10 20 30 that atf is im thinking of going with a low weight oil or a 0 w 30 if its made.

What issues did you have with ATF?

What exactly are you building for a trans?
