Transmission Fluid?

I'm gonna flush my 4-speed gearbox and refill it. What's the current recommendation on filling it up? Just regular transmission fluid? I've seen banter in the past about what people switched to in the 80's, 90's, etc...
Thanks!
Thanks!

Hi Hegg
I'm not going to be much help because I am going to do the same with my 5 speed and I do not know what the best oil is. I was hoping that there would be a synthetic oil available that would cut down on wear.
Anyone tried synthetic in a gearbox?

Zetec+ 2 under const, also 130S. And another 130S for complete restoration. Previously Racing green +2s with green tints. Yellow +2 and a couple of others, all missed. Great to be back 04/11/2021 although its all starting to get a bit out of control.

I have Redline MT-90 in my tranny. Shift engagement is quite nice.

Any of the synthetic gear lubes are good and Redline is best. Redline "MTL" is the correct equivalent to the original viscosity specification. The thicker MT-90 will work OK but the change will not be as good as with the MTL.
I have MTL in my 4 speed Elan and it makes the change even slicker than normal. In my 5 speed plus 2 it makes the normally slow change action much better and helps the weak syncros keep up.

I still use 80 weight hypoed-----ain't nuthin slipperier or better for the job --in my humble opinion --and with 160 000 miles on the super 7 tranny i feel it bears out my thinking --- ed <_<

Use the GL4 rated stuff only. The newer GL5 stuff can attack the brass bits in vintage gearboxes.

140W dino or ATF (mineral only). All are GL4 rated and okay to use in a manual gearbox. They differ in viscosity from the 80W stuff. 140W is thicker. ATF is thinner. Share the same GL4 lubrication properties though.
