Turned these codes off (after comparing to couple of other files I found). Now TC still doesn't lock because PCM senses misfires. I found one my spark plug wire is bad, maybe this is the cause. Damn, another 2 weeks wait time

I suspected low oil level but check it 3 times already, it's even a bit more than normal.
Here's daylight video I took today, you can see that at 1600 in 1st it barely starts to move

P.S. My TC doesn't want to lockup, only did it twice on a trip on a hot day, I read a bit and some people write it wouldn't lock until tranny fluid warms up to a certain temp, but I couldn't find such a parameter in HPTuners. How do you manually lock TC? Do you tap into S ("TCC Control" wire)? And, is there 12V or ground?

i know mine wont lockup my 4l60e converter til it hits the first mark... and i mean AS SOON as it touches it it will jolt into lockup lol. and mine would lock and unlock when i forst put it in, then i wiped the misfire tables and all my issues are gone. im following all the 80e build threads on here cause im swapping my T56 camaro over to a 80e. kind of a bastard child. 94 Z28/03 LQ4/02 wiring pinned for a 94 fuse block/ and a truck 80e connector lol

I have an aftermarket coolant gauge on mine and when I drive it cold (which I usually don't) it will hit lockup as the gauge clicks 113, anything below that and its unlocked. As I cruise at 50 and it hits 113, lockup happens instantly. So it definitely has a temperature minimum for lockup to happen.

OK test turned out to be performed quite easily - I just unplugged MAF intending to check VE tuning, and TC locks as it should, due to apparent absence of misfire detection in SD mode. So I need to read on desensitizing misfire tables a bit, I guess?
P.S. How do I make TC lock softer? Due to loose converter I like to lock early in 4th, but due to big drop in RPM lockup is very firm...

You see, here's the problem... I don't want to be sounding like jet fighter going at 2300rpm at just 35mph, so I want to use TC locking feature. But then rpm drop is so "big" that car jumps pretty hard. I'm sure it's not good on the tranny and TC clutch itself...
Is there any bad in going to stock min duty (50-75%) at TPS below 13%?

Vetal as weird as it sounds, the firmer the application of any of the clutches in the tranny the longer the clutches will last. That slip your feeling when you soften the shift up is the clutches slipping against each other reducing the amount of material available the next time you want it to slip. Although it may take a while to show itself(months, years, ....) the firmer the shift the better it is for your clutches and the less it is for your spine and neck

Update: still combating TC lockup. I've desensitized misfire tables by 2X and now it doesn't want to lock and I see this code appear:
[PCM] P0530 - A/C Refrigerant Pressure Sensor Circuit Malfunction
Seems like any least relevant malfunction disables TC lockup - creepy...
