Use your new found power responsibly and the tranny should serve you well.

Responsibility is overrated, lol

Bahah Yaris a/t's are cheap and easy to come by from a wreckers, I say go nuts!

FWIW you may want to swap out your trans fluid for a performance grade fluid like Amsoil or other. May give you some longer life from your trans should you grow an heavy foot!

That's the attitude. Lol. And, you're bang on about the trannies being cheap. I found one a while back on ebay that was from a wreck, something like 18000 miles on it for around $300.00 usd plus shipping.

I've always been an OEM trans fluid guy, especially after owning a Grand Caravan. It was ATF+4 or nothing. So, it's established that a good performance fluid would be perfectly compatible with the auto? Because, I would hands-down swap out the fluid for its superior properties if it was truly compatible in both the short and long term.

nothing wrong with OE fluids but your car is far from OE spec, not only with the bigger engine but the turbo as well. You likely will be fine with regular fluid changes as you have a cooler but I'm thinking more in the area of shear resistance from a better fluid.

OE spec fluid would meet sheer requirements the trans would face with the stock engine, in your case the clutches are working over time and I think a more sheer stable fluid would be some extra insurance. I have never heard of an issue with Toyota trans running Amsoil or even other fluid like Maxlife - they don't seem to be very sensitive to fluids as long as the fluid states it is compatible.

I personally always flush my used Toyota's with Maxlife simply because it is well priced and available locally to me. According to BITOG it is a pretty robust ATF and has always run well in my Toyota's (and Subaru's) that I have put a lot of mileage on. If I was in your situation I would likely go with an Amsoil product but it may be overkill. Just something to think about. If you are good with your fluid changes then you likely will never have to worry

Great info, Trevor. I'll definitely consider the use of a quality aftermarket fluid. The Amsoil might have a slight edge on the Valvoline product, but, like you say, maybe overkill. I plan to do some reading on the products. The fluid in my car is quite fresh. It's had a recent drain and fills and a couple more before that within the last 20 or 30K kms. I've also been considering the purchase of a performance valve body. It might be a very good first upgrade and one that should be fairly easy as it could be done without the need to drop the trans. Going to do some more reading on that too.
