I have a 2000 eclipse GS 5spd and this happens to me as well on cold days. Local tranny shop said it was the sycn mesh or some bushing. Neither one would cause major problems under normal driving conditions is what they told me.
that's "cold shifting". warm your car up at least a couple minutes before using it. you can also change your tranny fluid. contact RRE [Road Race Engineering, that is] for the "Scot Grey" mix [2qts Red line MTL and 1qt of BG syncro shift]. or pick up the BG syncro, it works well enough with the indiana weather.it just happens when the car is not warmed up like in the mornings, but after being on for awhile it works fine. if anyone has an idea that'd be great, thanks.
not necessarily, you just have to be on the right speed. you can't be running 35mph on your 2nd and decide to DS to 1st... -you know what i mean.Mine is from not knowing that your not suppose to down shift to 1st while still moving. I been forcing it into 1st gear for a long time before I found out I shouldn't.
make sure you're letting go of your clutch on the right time. Energy Suspension bushings and short shifter will help a lot. A really good ~$70 mod. It ensures that your gear is on!i have the original 03 gts transmission, and it seemed to be fine at first when i got it used a year ago, but now it tends to grind 2nd gear lots more often, coming up on a fluid change, so i will put some synthetic in there see how it goes
