Hi folks i am trying to find a solution to my SMT issue, I have a diagnostic done by Manawatu Toyota who have advised they found the following fault codes, P1873 and P1880 which they say relate to my SMT unit being worn and they recommend I replace the SMT unit,
Problem is Toyota no longer sell this part. There must be some other members in the club who have faced this issue and if anyone can assist me with a solution I would be grateful. The part code they gave me as the part I need to replace is #31390-0W012 .
Is there some backyard Guru who can re-condition the SMT unit or any other relevant solution please get back to me.
Also, has any done a manual swap with their MR-S here in New Zealand that might be able to help with info about where it was done and if they did it themselves how much it cost and what tools were required?
Cheers Drew

Re: SMT replacement
Hi Drew,
I have a pump and actuator assembly that was in good working order when I manual converted by 2002 SMT. It has had a new porsche acumulator fitted to it. You would still need to find someone to fit this and then set it up using techstream.
It looks like they have identified the pump needs replacing although the part number listed does not come up, 31390-0W010 supersedes to 31390-0W011. See http://jp-carparts.com/toyota/partlist. ... 2&fig=3107 for a breakdown of the SMT parts.
You will find/have found it difficult to find someone knowledgable on the SMT in NZ now.
I had a number of problems with mine starting with a clutch position sensor going bad. Then the accumulator went bad and that had the pump pretty much running all of the time (I suspect this is what is wrong with yours). After fitting the new accumulator it worked fine for a few months and then started dropping out of or not going into reverse, this is very inconvenient when trying to back out of a park. I gave up on the SMT at this point and did a manual conversion.
For the manual swap you will need with estimated used prices:
I spent most of a full weekend to carry out the work, fitting the manual shift cables through the firewall was a pain, really thick metal to drill through. I recall having to drop the fuel tank to fit the shifter cables and run the clutch line.
I dropped the motor and box out to make it easy to change the wiring harness, throttle body and clutch fork.
As for tools, figure on using hole saws/punches to fit the master cylinder (working out where to drill/position this is a mission) and shifter cables, a big jack and stands, an engine lifter to drop the engine and other standard hand tools like socket set, pliers and spanners etc.
It was a big job and that is not counting the research and gathering of parts before starting the job. It would be easier if you had a wrecked manual MR-S to remove stuff from.
Cheers

For the manual swap you will need with estimated used prices:
- shifter and cables $400
- clutch pedal and master $250
- clutch slave cylinder $50
- clutch fork $50
- manual linkage and selector for gearbox $500 (this converts your SMT box to manual) you may be able to get a manual gearbox with all of this on
- bracket for shifter cables $100
- custom clutch line $150
- manual engine loom $200
- manual throttle body $200

Re: SMT replacement
I know this is an old thread, but thought I’d share. The Porsche accumulator won’t work with the SMT system. The precharge pressure is too high for the SMT system. I tested on extensively and it will not work properly. Monkeywrenchracing has new accumulators listed, but currently out of stock. I have two new accumulators (manufactured specifically for the SMT system) I can ship. And they’re $80 USD less than the monkey price.
