Hi guys,

I checked with ShopKey yesterday & found the older model 300ZTT autos operated like a regular transmission, where the later models were shifted via a pair of solenoids controlled by a trans control module to fire the solenoids. (one on, one off 1st gear, both on, 2nd gear, one off, one on, 3rd gear, both off, 4th, does that make sense) if one were motivated, a system like the one above could be wired to operate like a paddle shift setup with relays to control the solenoids.

Keep in mind I'm talking about a manually shifted auto, not a BMW M3 style SMG (Sequential Manual Gearbox).

The simpler of the two I would think would be the non-solenoid actuated one. But, at least from a parts availability, the later model would/could be more easily attainable. I know there's some high horsepower 300TT autos out there.

I'm doing some more research today & this weekend to check on cable/linkage actuated shifter stuff, MusicMan, I'll post again once I know which usdm years would make more sense to swap.

I'll probably call McKinney this afternoon & try to pick their brains on the one they were involved in. I really like the way those guys operate, plus they have RB25 autos at the moment & could make the appropriate crossmember & driveshaft changes to accomodate their swap.

I'm thinking I'd like a S14 w/twin T28 based super 60 equipped RB26 with perf cir thrust bearings machined impeller/turbine housing with a clipped turbine wheel , auto with 2600rpm stall & a trans brake, thank you. :ylsuper

Ive been planing my rb25 swap now for over a year... got the motor just collecting dust in my garage.... still need an ecu... anyway i decided to plan this swap and make it a tight budget deal thats why it took so long plus my wife was 'bout to kill me by the time i finished my sr20det s14 (http://www.entuning.com) so... any way when i found out i could get a rb25 auto cheap i jumped on it then i found the car a s14 top of the line with leather and ABS and VLSD and ..... bla bla bla bla .. i found this 300zx auto-manual shifter kit and i think after i get this damn thing in the car i will probably try and make this shifter thing work.

i still havent compaired the z32 transmission contols to the r33 auto transmission controls... i was thinking of wiring the transmission to work with the z32 controls so i could easily add the shifter kit... let me know what you think about the kit or any info you can shair about the r33 auto wiring .... what exactly is your project slated as?
