'15 MT won't shift into 2nd at speed. Please help!

So I went to an Autocross event today and had some issues with my 6MT. The parade lap and the first heat were unremarkable. On the second, third, and fourth laps I tried to shift to second coming out of the first turn and was solidly blocked from making my shift until I'd slowed to about 15 mph. (I realize now I did not try double clutching.)

The car had no problem shifting to 2nd at parking lot speed, or parked with the clutch depressed or during normal driving on the way home. There was no unusual notchiness, grinding, or clunking while shifting.

I had replaced the transmission and diff fluids with Motul Gear 300 about 1,000 miles ago (2,500 total miles on car) and have not noticed any sort of leaks.

I have a Kartboy Short Shifter, Perrin Shift Bushing, and a Raceseng Topologi Shift knob installed. Clutch is stock. This is the second event I've run with this set up.


Anyone have any ideas on what it could be, or how to fix this issue? Thanks!

I'll make sure everything is lined up right next time I've got a day off. I'm just baffled at which of those would stop it from being able to shift under load like that.

Was the car fully warmed up (and then some?) Lots of reports that the Motul can cause cold shift troubles for some. That doesn't explain why worked for your first run, unless you held it in first just a touch longer the first time around (that would give the synchros a little more time to get up to speed - it's how I deal with winter shift blues on mine...)

There is a possibility it is the reverse lock out. I had the same issue with mine. I had times where 2nd was locked out while driving hard. I believe the reverse lock out is adjusted just a little too far to the left, allowing me to travel past 2nd toward reverse. It's an easy fix, worth trying.

Car was fully warm. Idled for 20 minutes before parade lap, then never shut it off between runs. It probably took me coasting about 10 seconds to slow enough for the shifter to slip in gear.

This actually might be it. It is a bit further left than I would have liked, but it was such a pain in the ass to get to I figured I'd just deal. I'll get it shifted tomorrow after work. However I did try angling to the right while shifting and also working the shifter back and forth between gears, and still couldn't get it in gear.
