Engine seems to downshift on it's own.....

Don't get me wrong, I really do love my TSX, this the one major hangup I have. Any ideas?

Solution: Accelerate harder.

These downshifts are not smooth and predictable, they're on the jerky side. As a result, I frequently find myself sliding over to SS to hold a gear - something I would rather not do.

OK - Allow me to present a little food for thought here. The biggest wildcard here that needs to be addressed I think is the combination of the Drive-by Wire throttle input and the computers' desire to deliver performance and protect the engine. I have found that if I use less hard pedal action v. slamming it and pay more attention to where I'm at in the rev curve/torque to the wheels position I can get a lot of control over acelleration & smooth shifting simply by leraning how to properly use my right foot. I've found that the computers, etc then seem to antipate what I'm trying to do to the point where I seldom use the SS in passing or even when I "get on it." I'm not saying that it was easy to figure this out and that I don't get the ocassional hard shift but they been rarer & rarer and my driving style has become very smooth as compared to when I first got the car.
I figured that the brains back at Honda knew what they were doing and that all things consided if I was to look for the source of the "problem" I would have to admit it was more my ignorance and lack of understanding rather than a "car problem."
My next mod will be the CPU reflash which should allow me a longer & flatter torque curve. This will afford me the desired option of always being able to "catch it" on the up curve with plenty of headroom and up-torque control. Remember guys... it's only a 4-cyl. Any damn fool can drive a 300-to-500 hp 6cly/8cly torque monster. That ain't no fun let alone a challange.
P.S. - The SAAB Sonet had an English made V-4 engine. Nice car.

I guess I'm one of the few that appreciates the downshifts. I live in an area with a lot of steep hills, and I was very hard on my breaks with my last car. I've noticed a big difference with the TSX. I wish there was an option to show the current gear on the display even when you aren't in sport shift mode.

i think a lot of epople here missed the point of my post originally.

how long have you had the car? i've had it since december, i guess though, i just recently started doing country driving, and just noticed it. i'll get a better feel for it after a few more rides.

I bought it in August '04. I don't put many miles on a car any more as I have no free time to go crusing, etc. I would suggest that if you haven't done so yet, talk to a sr. service tech or someone like JTso who have a better understanding of "how" some of the car's systems work, i.e. the tranny control systems. An example would be how, when applying the brakes you can by modulate the brake pedal and take the load off the front discs and load the rear discs causing the back-end to squat and tuck in under straight line & moderate turning braking. When I last checked the OEM pads before I upgraded the braking system, the rears showed twice the wear than the fronts. As for what I've said about the shift points, I'm only having an ocassional problem with the low rev hesition which I think would be eliminated if I do the cpu reflash.
All in all I think once you become more familuar with the TSX's tendancies and control systems you'll apreciate our little road machine even more. I'm glad every day I drive her that I bought one - rattles, buzzes, etc. notwithstanding.

RacingBrake up front, Powerslot rears, Goodridge SS brake lines, Hawk HPS pads & OEM brake fluid. $700.00 +/- for the parts and I had the dealer install it for $450.00 (yes I could have saved some bucks). At this stage of my life I decided to have the dealer do the work & I established good communication channels with the Head Service Guy (better to be friends v. enemies) and also kept the car under their "service history." I've got about 500+ miles on them and after taking a good 300+ miles to seat them in I'm in Brake Heaven. I'm a bit old school - Before I spend $$'s on going faster I want to be able to stop faster.

Good luck on your mods & enjoy!
P.S - RacingBrake nows shows a slot/drilled rear disc.
