6-speed/3.63 speedo gear fail *Now with more win than ever!!!*
Did you work with Bill @ Miataroadster? We are talking about a mechanical sender, correct? One of the pics on this thread looks like a electronic sender.

Read my prior post, #7, those are the same part numbers Ben is talking about. It works. It's mechanical. The speedo reads about 2 mph slower at 80mph according to the GPS but that's about it.

Very interesting, I have the white 19 tooth gear and the offset housing but they didn't mesh. I'll have to check my part numbers tonight and bounce them against yours.

Just bought a 6 speed gearbox + 3.6 diff
after reading all off this i don't understand the problem...
A lot of effort to get a suitable transgear.
The 89-91 miata has a 20 tooth gear (including transmitter) according to solomiata website... Isn't this what we are looking for.
As for 89-91 owners.. We need an other gear (with 17-18 teeth..)
That could be tricky...as it is only found in 84-85 RX7...
Is this PNP???
Correct me if i am wrong...

1011-17-442A - This is the sleeve/housing that will position the gear in the proper location to engage the gear within the transmission. If the sleeve that comes in a 5-speed transmission is used, the smaller 6-speed gear will be free-floating and will not engage. Thus, no readings.
M502-17-441 - This is the actual gear.
9922-20-214 - Spring Pin for holding the gear in the sleeve.
9958-60-8166 - Oil Seal for inside the sleeve.
1011-17-443 - O-Ring for the outside of the sleeve.

I picked-up another 6/3.63 combo for my daily to make runs from Dallas to Houston more tolerable at 90mph.

Ok, I put this in the turbo car yesterday and it's a little off. It reads 80mph at 75mph (according to my G2X). Can it get any better or is this the best we can do, which is good enough I suppose.

Weird, that was the same gear and tire size used on my NA, however I had the opposite condition, the speedometer showed around 78 mph when the GPS showed 80 mph (as posted above). Maybe pop open the cluster and adjust the needle? I'm sorry, I don't know what else to suggest, mine was only 2 mph off so I never messed with it. Or if you still have the M503 gear you could try swapping it out and see if it gets things closer.

This is pretty good and you helped. My last speedo read 15mph low at 80. I'm going to buy another set for my daily and it's pending 6-3.63 swap.

Hustler, where are you finding all these 6-3.63 swaps here in Dallas? I realize you're probably buying the gearsets from MazdaMotorsports, but where is the abundance of 6 speeds for sale?

The daily set-up is going to be part of "operation hypermile" with the VVT & MS3X swaps coming down the pipe.
