Gear lockout!

[marcusm86]

Sorry if I wasn’t clear earlier. At 30,000 miles, I replaced the transmission fluid with OEM Honda MTF—2 quarts plus a little extra. The transmission lockout happened yesterday after I was driving the car pretty hard. The video I posted was taken in a parking lot, and I wasn’t even going 5 mph, but that’s how hard it can be to get into 1st gear sometimes.

As I mentioned before, I suspected the delay valve might be the issue. I didn’t mean to say the transmission feels hesitant; it’s just that after driving hard, when shifting from 1st to 2nd, the gear wouldn’t go back into 1st again. I was at a stop sign, and the car just wouldn’t engage. That’s why I mentioned the mod I installed to see if it could cause any problems. I included as much info as I could in my first post.

I assumed this might be similar to an issue I had with my EVO when I was using Redline MTL (I think that was the name). After upgrading to the EVO 9 master cylinder and removing the delay in the slave cylinder, the problem almost completely went away.

Today, I turned off the Auto Rev Match, and the shifting improved drastically. The video I posted was recorded before I disabled the rev match. I shared it to see if anyone else has had a similar issue. I also want to be clear that I’m only planning to use OE fluid in the transmission.

I have had issues getting the car to go into first below 5mph before with rev match on.. I've since removed the CDV and the CMC damper - i seem to have very few issues now, but they are not gone.. Most of my issues now seem to occur when the fluid is not warmed up (cold start or just started driving for the day) i think i will be swapping fluid here soon (i have about 8k miles on it)

Just to be clear this wasnt happening super often for me.. just enough to convince me to make these changes i already was planning on doing.

I will buy that tool with the adapter—sorry, I jumped the moment you mentioned it! The adapter is a specific one; where can I find it? I’m also thinking of going with DOT 3 since I drive mine daily. Can this tool be used on the calipers as well? Because as you mentioned it was not easy to use the vacuum one with compressed air.

Motive doesn't make an adapter for Hondas, but there's info on adatpers here:

AGM seems like the easiest route for a quality adapter.
