As you can see i dont have a turbo model, but i know my car can handle high rev's.

Anyways, my shifting is a bit strange. I was told i need some type of anti-friction on my tranny. (or gears) The problem is when im running my car from 1-3 at high rev's each time i switch gears (1st -> 2nd) i have to seriously push the **** down until i feel it snap in place. (same goes with 2nd -> 3rd and so on). Im pretty sure thats common in most cars when you driving at high speeds... but i dont think this is right.

So if there is something i can do, then ill do it. Oh yea, my friend was talking about this NEO Synthetic Anti-Friction oil/lubricant .. w/e it is. But we were unsure if the rx7 tranny would be able to support that liquid. What do you guys think? Thanks in advance!

I have not used Neo, but highly recommend Redline MT-90 for our transmissions. If you need even more slickness in the tranny you can also use Redline Superlight weight shock proof gear oil, but shock proof may be too slick, if you are a slow shifter.

You will want to avoid GL-5 non synthetic (or semi-synthetic) gear oils in our transmissions, as they tend to be high in sulfer content (a anti-wear ingredent- that can break down eating our syncros). A GL-4/GL-5 combo oil is fine, just avoid pure GL-5 gear lubes.

Some pressure is normal when going into gear. You are not driving a FWD car with lame cable shifter that mushes up the shifting. However if a conventional GL-5 gear lube was used (instead of a GL-4 or GL-4/GL-5 combo oil) the syncros and brass parts in our transmissions may be damaged.

Try adjusting you clutch peddle. Its under the pedal itself. This will give you more play.

thanks IceMark is it possible to change the tranny oil even if its not due? I heard that was harmful to the transmission. Is there some type of friction or additional fluid i can just insert (without flushing, or changing the t-oil). That was a helpful note you mentioned. I appreciate that.

Dave, i dont think i need to adjust my clutch pedal. But that could of been a possibility, thanks anyways! ^_^

the harmfull tranny change is an urban myth, people change their tranny oil because they think something might be wrong. Then when the tranny breaks they blame the oil.

Icemark

As snowball covered, there is no reason not to change the gear oil at any time.

I personally recommend gear oil to be changed every 1-2 years or 12k-24k miles (depending on driving style and driving conditions) for a street driven vehicle.

Just as a side note you might also want to check the conditions of the shifter bushings. I'm dealing with those right now and after that i'll be getting a flush and replacement of the tranny fluids. but the symptoms are very similiar to what i'm going through.

The previous owner had left the shifter metal on metal which made things really difficult to shift, so i was able to get a bushing set from mazda (warning mazda only sells the lower bushing in that set), with just one bushing (i'm working on getting the others) shifting became much easier. So that's something else you may have to look into.

where is the transmission reservoir located? im such a noob since idk how to replace my tranny fluid. grr.

Icemark

There is not a Transmission reservoir. The transmission itself holds all the gear oil.

basically put the car up on stands or on a ramp and there's a bolt on the tranny that you have to undo and put your finger in the hole the oil/lube shouldn't be above the bottom of the hole. if you don't want to deal with the mess and all that get it changed at a shop. (check either the haynes manual or even the factory service manual for specifics).
