any non-synthetic 75w-90 gear oil. GL-4 will work the best if you can find some.
Manual Transmission oil
Hi I have a 1965 mustang with an original Ford 4 speed. I want to change the transmission oil, but I don't know which oil I should use.
Also, I daily drive it pretty much every day, not really in the winters but I will need an oil that can operate at lower temperatures (Nothing crazy, like I use 10w-30 and it works fine. I live in SLC, UT if anyone is familiar) But I have noticed that when I change gears in the morning (fairly cold), it shifts hard. But then warms up and functions better. So i know that is normal, but i am debating about switching to a lower viscosity. Anyways, I would love to hear any input! THANKS!!

You can use Mobil.1 75w-90 gear lube,
It works great,

that will work. synthetic doesnt shift as good in the old brass ring transmissions.GL 4 is recommended for the top loader. Check with NAPA.Brian
I'd recommend giving the Mobil 1 75w-90 ( or the Mobil 1 75w-140 ) a try before making a blanket statement . I've been using it for 20 years of hard use in numerous toploader and T-10 tranmissions with no shifting issues and no measurable wear on any internal tranmission parts.

I do "not" make blanket statements. Call Dan Williams Toploaders at 828-524-9085. Dan will tell you do not use synthetic in a toploader. Dan has been building toploaders for over 40 years. Dan knows more about toploaders than we will ever know. They shift "better" with non-synthetic, i know i'v tried both.I'd recommend giving the Mobil 1 75w-90 ( or the Mobil 1 75w-140 ) a try before making a blanket statement .

Now, now, don't get all riled up. With all due respect to Dan, another nationally known toploader builder/authority by the name of David Kee, will tell you that many people run the synthetic lube with no problems, and that while others have not liked it when shifting fast (I never had that problem), David says either will work just fine as far as causing any problems internally.I do "not" make blanket statements.

Many experts that have been using conventional oil and lube for all their lives, are demonizing the synthetic products without showing any legitimate reason for doing so, except the dislike of the unknown. I like to base my statements on what I personally have experienced, and not depend on any expert to substantiate or refute what I have seen with my own two eyes. You say your own transmissions shift better with conventional lube. I believe you and respect your experiences. My experience is opposite of yours, so we are both happy going down the road each using a different product we are happy with.
When my own manual transmissions go belly up due due to synthetic lube, then I'll eat a big helping of crow. But that doesn't seem likely to happen. If 20 years and a cumulative 500,000+ miles doesn't ruin a transmission using synthetic lube, then I doubt another 20 years is going hurt either.

first of all Dan Williams taught David Key about toploaders. David Key wne to work for Dan and Dan Trained him. secondly all i said was non-synthetic will make the toploader shift a little easier. thirdly i'm not all riled up and you can use whatever oil you like and so can anyone else and i will use the stuff that makes toploaders shift a little easier. you can also call Dan to verify what i just posted and you can call David Key. p.s. you type like your really cranky. :wave:Now, now, don't get all riled up.

i never said it would blow up, i said non synthetic will make it shift a little easier. the brass rings like a little friction to slow them down. also a toploader needs from .003-.0035 clearance between the gears and mainshaft.Changed to synthetic 2 years ago.

Hey you did too say "She's gonna blow". I read it on every post you make (avatar). Don't run out of ibuprofen and step lightly on left foot.i never said it would blow up, i said non synthetic will make it shift a little easier. the brass rings like a little friction to slow them down. also a toploader needs from .003-.0035 clearance between the gears and mainshaft.

"Synthetic oil is very popular in the automotive industry today. The way a Toploader is designed it needs a certain amount of friction for the blocker rings to synchronize shifts. We have had people try synthetics and say it works great and some say it doesn't work at all. Everyone agrees that standard gear lubricant does work. The biggest determining factor as to whether it will work or not is the driver. If you drive your car normally and shift it normally synthetic would be a great choice. If you drive aggressively or want to shift fast then synthetic may not work well. If you try synthetic gear lube and it does not work for your driving style drain the transmission and try standard 80W-140 gear lubricant.
Oiling Specifications
Just checked with the local Ford Dealership... $21.35 per qt. in stock
As has been said, Ford specs out GL-4 for the toploader and it is better suited to the blocking rings than the current GL-5 lube. GL-5 will not make the tranny "blow up", but if it's available, get the GL-4.
I bought mine from amazon when I was ordering some other stuff. IIRC, it was only $22 at the time.
