Ok I honestly believe this is all in my head and that's why I'm screwing up but hear me out. Cuz I need opinions and I don't want to continue ignoring it.

I've owned the car for about 1 year 8 months. But it wasn't until last month that it became my daily driver. As far as I'm concerned I never had this issue until a week or two ago.

Going from 1 > 2 > 3 > 4 > 5 > 6 is smooth and no problem. It's rare that I even go to 5th or 6th. Literally drive to work and home and don't spend much time on the highway to go "fast". 55mph-60mph is probably the highest I go on a daily basis.

Now the few times i make it to 5th and 6th I feel when downshifting into 4th its not going in unless i slowly do it and focus enough if that makes sense, it's weird. It's not rough, it just won't go in on a natural move/shift. I already made the mistake of going from 5th to 2nd (only once) because of this and yesterday I tried to do it without overthinking it and when I look down I'm on 6th -__- lol.

Any suggestions. Not having this issue at all going up, just down

 

I've experienced this on a few AP2s I've driven. They all have perfectly working hydraulics with no leaks. Check out this thread: https://www.s2ki.com/s2000/topic/886...ft-resistance/

Particularly the bit about the synchros.

 

The gear shift is "center sprung" for want of a better term. 5th to 4th is straight back with no sideways pressure on the shift knob. Don't grip the knob, just move it. Don't try to put it in 4th, just let it go there naturally. Pull straight back with your fingers only on the front of the knob. This is the same way to shift from 3d to 4th. As you get out of 5th the lever will spring left into the 3-4 slot and continued light pressure to the rear will put you in 4th. A one-two count.

This makes it sound like you mean 5th to 4th is a straight line shift, on the same leg of the H pattern as each other. I know you didn't mean that. But in case anyone is confused, 5th to 4th is of course a 'diagonal' shift, but Chuck is saying don't try and move the level diagonally. Move it straight back out of 5th into N, let it center itself naturally, then straight back into 4th.

You don't put side pressure on the knob, let the springs do that for you. Make it a two step motion, out, then in, but do it quickly.

OP's picture of that thread pretty much illustrates what I believe I'm feeling. Just a bit confusing when everyone else seems to be experiencing a similar issue with a slightly different reasoning. What bugs me the most is that it only happens down to 4th. Not up or down to any other gear, so I'm left with pretty much no answer/solution. In the meantime I'll just take care of all the fluids and wait for a clutch job since that seems to be the most concrete answer.


Gonna try to follow this advice without overthinking it. Just use my fingers, hopefully i notice a change. It's funny I had a dream last night that i was doing exactly this haha

lol i knew exactly what he meant but now that you mention it i see what you're talking bout.

In regards to the two step motion that's how i'm doing it. just not as fast because im too focused on making sure it goes in the right gear. i literally have to look down. its so uncomfortable
