Any additives needed when changing MT fluid?

Is there anything else needed to be added to the fluid when you change it. I swapped my fluid out for Royal Purple Syncromax the other day and it seems like I can hear the "clunks" of the gears when I shift. Or even when I just engage the clutch to take off. And it didn't really seem to take away the notchiness like I thought it would.

And I know the correct amount is supposed to be 2.7 quarts, so I marked a small container with what I measured out to be 2.7 quarts. The car was basically level, maybe slightly tilted down to the back if at all. Fluid drained right out but filled the container more than 2.7 quarts. Not by much but some. So when I went to refill with the RP stuff I pumped in 2.5 quarts knowing I was getting close. And since the car might have been slightly tilted back that it may start coming out of the fill hole sooner than it should.
Kept pumping and got to what I thought would be right and it still never came out. I measured what I still had left in my bottle and it was actually less than 0.3 quart. So technically I put in a fuzz to much, but by what I took out I may have put in a fuzz not enough lol.

So should I have seen fluid coming out of the fill hole once I hit the 2.7 quart mark or no? Do I need to go back and add until I do or is it good. This also has me wondering since I was hearing that clunking noise.

Thanks

Ive read, once youre at the 2.7qt mark, it should be about a 1/4" below the fill hole

Ford has an additive called XL-18 especially for the MT-82 manual transmission. About $20 at your Ford dealer.

Op,

I am looking at using the same fluid. I read royal purples site and they say no other friction modifiers are needed. Did you ever get the additive or not? Did the transmission ever get better or did it explode? I know this thread is a little old but I used the search function and this was my exact question before I use this product.

If you go to either of their websites they do not recommend an oil for the MT-82. I typically run amsoil.

75/90 is way to thick for these transmissions

I really just want to know if the royal purple syncromax is good to go with no additives. Anyone who has had experience with this please give us some feedback. Thanks

General rule of thumb with amsoil is hot it gets where you drive. For Texas heat, MTG would be surely a good idea. For every where else, Ben Calimer suggests MTF synchromesh..without any additive. Or 2:1 ratio of MTF and MTG if it's really hot, but not as hot as Texas.. No winters what so ever.

I'd say try 2 quarts of MTG and 0.7 of MTF and see how it goes.
