I think the "clunk" happens around any rpm, and pretty random. When I do bring the engine speed up to 4K+ before shifting, I can get my shifts smoother by not waiting for the gear to "catch." However, if i wait for it to "catch" the engines already spun down too much for a smooth engagement.

From what i read, it seems the clunk is normal - and likely due to the fluids not being changed and/or possible some tweak to shift lever. I just noticed that I have an aftermarket boot - the oem boots don't come with white stitching right? Perhaps I have a short shifter installed?

Changing the brake fluid too, right?

Thanks for the tips guys; I'm gonna change out the fluids tomorrow and report back. I'm going to regrease the shifter Saturday then report back.

Dwight: should the brake fluid be changed? I always figured its harder to abuse brakes than the rest of the parts I mentioned.

Brake fluid should be changed every 3 years, and the car is 7 years old... probably due.

Hrm....interesting.

I guess i'll sort out this transmission thing first and then work on that. I have a feeling the engine mounts are going to crap too - the car likes to "Shudder" for maybe 0.5 secs before it shuts down.

As far as abusing brake fluid, if you run the brakes too hot, you boil the fluid. The brakes will get spongy and such. This is unlikely to be an issue unless you track the car.

Brake fluid should be changed regularly because it is hygroscopic, so it picks up moisture from the air. As a result, it will get water in it and can cause rusting. I've been negligent in this in my RSX and the piston in the front driver's side caliper seized. (In addition the water will lower the brake fluid's boiling point.)

Changing brake fluid is pretty easy to do, but it's also pretty easy to forget about.

I got all the fluids changed out over the weekend and i regreased the shifter. Didn't seem to see any damage, may consider just getting a new assembly as it isn't that expensive.

The shifting seemed to have smoothed out after the oil change but the notchiness came back with some use. I'm thinking i'll try GM Syncromesh next time or maybe towards the end of the summer and flush it out myself.

Other points I noticed: the gear "catch" feeling occurs more likely when I upshift and i rarely feel it on the downshift. Based on shifting habits, I pause longer in between shifts when I downshift. Perhaps I should try to adjust the freeplay on the clutch to let it out quicker and allow the syncros to do their work quicker?

Sounds mostly normal to me. Good ol' xviper/repiv recommended waiting a bit on shifts as you've mentioned before actually putting the shifter into a gear. Definitely don't force it.

Another thing Billman's mentioned in the past is rusty splines in the trans - not enough grease from factory so when they dry out, shifting gets bulkier.

How do you resolve rusty splines?
