Non MB trans to MB engines
Deep overdrive on these transmissions is worthless without a high ratio rear end to go with it. The 2.47 and 2.27 rear ends can’t possibly work with the TWO overdrive gears. You’d have to be going REALLY fast. So 3.27, 3.46 and even higher ratio rear ends would be required for them. Like maybe some of the swing axle rears from 6-cylinder cars. And good luck finding them in an LSD.
Ratios are: Gear Ratio 1 4,002 2 2,108 3 1,380 4 1,000 5 0,780 6 0,645

I cant speak for any of the other engines. But the M120 V12 runs really nice with the 722.6 automatic in 5th gear at 0.83 with a 2.47 diff. Gas mileage is really high in that configuration. Using a 3.06 diff I can get pretty close to the same results. But on the low gear side it would be the equivalent of having about 5.0 for first. I was looking into a T56 and I find the opposite problem in the low gears. Finding gear sets numerically higher that 3.06 for the large case MB's is difficult. The V160 Getreg used in the Toyota supra appears to have a more reasonable set of gear ratios a range of 3.827 to 0.793 but not sure how much torque it can take. Also trying to find specs on some of the Nissan Z transmissions.

This one looks just about right. Too bad the bell housing is integrated. Still looking for torque ratings on this.

On the lowest end, an LS was making about 285lb-ft of torque, while the M117 made about 336lb-ft on the high end. That site advocates for a more mordern LS/LM/LQ/etc. motor, which is likely making far more torque than the make 336 of the most stout, non-AMG M117. Torque wise I think that gearbox is more than up to the task. The problem at this point is if input shaft is: a) too long; b) too short). Too long can be deal with by increasing the thickness of an adapter plate. Too short and you're looking at a custom input shaft. Unrelated to the above, I've had to drop my autobox to track down a mystery leak from the rear of the motor (the rear seal is fresh, it looks like the issue is from the rear cover and the upper oil pan, where I did not apply any RTV since there was technically the upper oil pan gasket to the rest of the block. What a nightmare that was. If I didn't need this car up and running yesterday 3 months ago, I'd consider some time spent looking at other options for a manual box. Unfortunately, the firm that i work for goes to trial Monday (my birthday, and the wife ain't happy about it) and as per usual we're doing all our prep last minute so I have little time to devote to this car. Needless to say, combined with the lack of satisfaction driving something with a slushbox, the remove process is equally a pain in the ass.

I've used the cd009 behind my 1uz starion with no complaints other than size.
Here is the link to the kits mentioned above: thekangaroosteam kits

Size? Too long, too short or too wide? -cth

RE: "CD009" gearbox
This designation, which seems to be used in the aftermarket, is but one version of the Aisin AZ6 trans. The AZ6 has been used by Toyota, Mazda, Nissan, & Subaru. In each of the versions there are different main case castings, different tail housings and shifters. In the Toyota/Mazda/Subaru versions the bell housing is a bolt-on! |

Long sigh.
The CD009 has nothing to do with the AZ6 transmission. It is not built by Aisin and the only thing it shares in common with the AZ6 is the country it's built and the number of gears it has.

If, in fact, the CD009 is not an AZ6 version/derivative, what is it? Built by what supplier? Why are the ratios identical - to the third place - in all 350Z/370Z/G35 gearboxes from the CD003 thru the JK41B (2002- end of series 2017/18?). The CD003 - CD008 boxes are known to be AZ6s. |

I have no idea what AZ6 transmission you are talking about.
S15 -- 6 spd -- 3.626 2.200 1.541 1.213 1.000 0.767 RX8 -- 6 spd -- 3.760 2.269 1.645 1.187 1.000 0.843 Miata 6-spd -- 3.760 2.269 1.645 1.257 1.000 0.843 BRZ AZ6 3.626 2.188 1.541 1.213 1.000 0.767 These are all AZ6 transmissions CD009 6MT -- 3.784 2.324 1.624 1.271 1.000 0.794 With the exception of 5th gear, Direct drive, none of the ratios are the same to the 3rd decimal place. I have no clue who makes it. It isn't Aisin. The only AISIN AZ6 that nissan used was in the S15 silvia listed as the FS6R92A. The 'CD009' or JK40/41c or CD00x transmissions are listed as FS6R31A Nissan makes their own manual transmissions. There are some exceptions: EG the AISIN AZ6 for the S15 silvia and they used Borg-Warner/TREMEC to produce the T-5 they used in the 300ZX Turbo Z31 as well as the S130 280ZX Turbo. Shown are pictures relative to the AZ6 and CD009. Not only are they not even close in size compared to one another, but the shifting setup between the two is quite different. Given this, what evidence do you have that any of the FS6R31A transmissions are AZ6 AISIN transmissions?

Given the side-by-side pictures I must indeed yield on the identification. Thank you.
If those two examples are in your possession, at your convenience would you try to determine the mainshaft-to-countershaft center distances for each. |
