Just trying to find out if mr2 spyders commonly have problems with there sequential manual transmission(SMT) and if so is there anything i can do to help prevent it. The reason i ask is because my new spyder had to be towed today to toyota because the warning light on the car indicated there was something wrong with the SMT. Dont know if this problems could have anything to do with getting the car's computer replaced about 2500km ago???

my mate had the spyder and had a gearbox problem on it after he "discovered" how to shift quicker on it.

I think the best way to keep the gearbox healthy is make sure you are not throttling AT ALL when you shift gears. His box was fine until he started shifting like this > revvv, shift, let go accelerator for split second to let the next gear catch> rev/ when it should be. rev. let go of accelerator, shift, let next gear engage, then rev again.

a bit confusing but after he started doing the "quickshifting" his gearbox broke. so dont do it :P

doesn't make any difference in the way you shift and never try and replace the smt fluid.

some smt computers were faulty and needed to be changed under warrenty.

i've never had a problem and i drive it hard and its turbo.

hmm weird i thought the whole purpose of SMT was to not let go of the accel while shifting lol, like auto but you have control over gear changes.

what is the actual problem with it??? does it still drive at all?
you can leave your foot down as it lifts the throttle for you, like down shifting it will rev match and blip the throttle...

The problems i have seen in my time with toyota with the SMT system have been many. The early model SMT ECU's (mounted next to the engine ecu under the passengers side storage bin) were a nightmare, and the ecu's have been revised 6 times over the course of the 5/6 speed spyder range. The next problem has been gearboxes breaking due to insufficient fluid in the accumulator (the assembly under the airbox). We also have had a lot of trouble with shifting etc after a private workshop has changed a clutch, but the system hasn't been told to re-learn how far to push the clutch lever etc.

Other than that, it has been mainly lack of maintenance, people spilling drinks in the shifter assy, holes in the convertible roof getting water in the electrics, not using the sst to remove the accumulator lines, and people running the wrong fluid in the SMT system.

I have done the SMT relearn proceedure a couple of times, at leat once a year, just to keep everything in check...

SMT fluid should never be changed unless there is something major wrong or the pump is being changed.

Yeah, that is very true, but the level should be check from time to time.

to answer your question, YES,,, they have lots of problems , and I doubt there is much the average owner can do to stop them, apart from sensible driving and not pouring drink down the shifter mechanism (see that one too)
we have fixed a few Spyders where dealers have given very high quotes to replace almost every part of the transmission to fix relatively minor problems.it seems some of them are incapable of diagnosing the faults (which are many & varied)
Re-learning after a clutch change is a common problem .
i have found backing off just a fraction helps the shift quality enormously.
If you are looking to buy,expect cars with over 100,000km will be about ready for a clutch change. also, by 150,000km, they will need syncro replacement inside the box as they are hammered harder than in a stock box.

Mine (touch wood) hasn't had any problems besides a APS sensor which gets the signal for the DBW (Drive by wire) The SMT design and workings is the same as what is used on the BMW's, so I am told.

But if I was to have a problem a manual conversion would be on the cards....

Thanks guys that helps me out heaps!! in answer to what is exactly wrong with the car well i had left the car for a couple of hrs parked after giving it a bit of a trashing and then came back to it and warning light for the SMT was on. Before i got it towed i tried to drive it but when i stoped at a light it wouldn't change gears and would only stay in N. Had to switch off the engine and restart it and then i was able to change gears. Hoping this isn't going to be a reoccurring thing to happen or im just going to have to get rid of the car!
