Hello everyone, I have a 1994 Honda Del Sol Si with the D16Z6 and S20 Trans. I just replaced my transmission with a new-used transmission from a different civic. I also replaced the clutch and pressure plate with an OEM replacement from Exedy, and replaced the throwout bearing and rear main seal, as well as the pilot bearing on the flywheel. I filled the transmission with Genuine Honda MTF and it shifts very well through all the gears and does not pop out of gear. When I am accelerating, especially in first and second, as well as a little in third, I hear an odd metallic grinding or clicking sound.

I have a video of it and you can see it starts right at 2500 RPM in 2nd gear. After driving around for about 15 mins, it changed to where it would make that noise through the entire first gear, and not at all in second. It seems to fluctuate, sometimes it doesn't start until 3500 RPM.

By the way, it does not make this noise when coasting or in neutral, only when I am accelerating. It is most noticeable in 1st and 2nd and partly in 3rd. I am sure the wind noise might just mask it at higher speeds. Could this be an axle, or the transmission itself? It did not make this noise before when accelerating, and the only pieces I removed were front end pieces like the axles, tie rod ends, and lower ball joint.

Sounds like you bought a bad used transmission. Either roll the dice again and buy another used one (and hope it works properly), or spend the $$$ to fix it even though this option may be more expensive than purchasing a used one... at least you know exactly what you have then.

Transmission needs to be rebuilt.
