Here are links to sites that host online manuals for RX-7's.

Dunno, but If i were registered at a mustang internet forum, i'd list my car as a 90 GTU rx-7. I wonder how many people would tell me to find an rx-7 internet forum.

If you listed your car as a 90 GTU RX-7 on a Mustang forum, and then asked how much oil the transmission takes, you would probably get a bunch of answers much less civilized than what I am typing now.

Stupify,
just incase you need to tip your decision scales over,
Use REDLINE,
I have 88 TII, and know at least 2 other people that own an identical car. We all use REDLINE. The results are absolutely the same. The first thing you will notice, metal portion of your gear shifter handle will be much cooler due to cooler operation.
My TII uses aproximately 2 - 2.5 quarts

You can list more than one car in your profile if you like, just as long as the names are short. Also, you can put them in your signature. See my profile and signature for examples of both. Note that you still need to specify which car you are referring to in your post if it is not obvious to the reader.

my 2nd gear synchro is beginning to 'go'. i cant really compare it to anything though.. ive only had the car for a few months, and within the first few weeks i changed to redline MT90.. it made a noticeable change, and i was suddenly able to downshift into 1st!
im beginning to wonder if the 2nd gear synchro is due to the redline fluid?!
how can anyone possibly know/prove that its the fluid eating the synchro?

not saying redline is bad, i use redline and it was a noticable improvement over the crap that was in there.

My .o2 on MTL tranny fluid. My experience is with VW transmissions and I have used Redline MTL in several cars with excellent results. These were all A1 and A2 cars (i.e. up to 1992). There is the same argument about the pros and cons of Redline on the VW forums. The Redline MTL is designed for the early cars that have synchros that will not tolerate some of the common additives. I have never had a transmission fail after adding MTL and some of them were driven for 4 years.
I also used MTL in my '89 Saab 900 Turbo transmission. I have been driving it over a year now and the results were dramatic.
The Redline website used to have a good technical article about this issue.

These guys say they can ship Redline to you.

I've had NEO in the transmission of my (now former) 240sx. Tranny was fine. I drove over 50k miles w/ it before I sold the car. No problems or complaints w/ that product.

this probably doesn't help much
but I know that the Subaru and BMW community LOVE Redline.
I do know that a synthetic tranny oil will be more "slippery" than dino oil, meaning your synchros won't be as effective. But otherwise, I can't see it doing damage.

I've had mixed results with Redline MT-90.
My first experience was with a fresh rebuilt transmission in my NA 86. Redline made the gear shifts more notchy after the switch from Valvoline 75w90.
My second experience was with my GTUs. The car had 97,000 on it and the 1-2 syncro was frozen. The transmission would grind on every shift from 1-2 or 2-1. I put redline in the trans and presto! The problem disappeared completely in one day. I'm at 115,000 miles now with no problems.
Third experience is with Triangle Power's 90 TII. Redline made his box shift more notchy than the dino fluid that we pulled out.
So what does it all mean? Redline seems to work wonders for worn + tired transmissions. It has great cleaning properties. It might not work as well in rebuilt/tight transmissions.
One reason to explain this is that MT-90 is very thin compared to 75w90 gear oils. I've heard that MT-90 doesn't adhere to the syncro's as well.

I thought MT90 IS 75W90, so how can it be thinner?
So which NEO was used? HD or RHD? Just curious, cos I'm thinking of switching to NEO too, but not sure which.
I currently have MT90, noticeable difference, but nothing tremendous though, I like it.
