Problems with certain cars not loading when mods are enabled

Since we are using machine translation, it may be in strange English.

I made a mod that adds a 4-speed automatic transmission to my Pessima.
When I enabled the mod, the car didn't load and only the color of the car changed.
So, I tried to find out the cause, but I couldn't solve it myself, so I will ask you a question.

Watch the video for more details.


I cleared the cache, but it didn't work.
I think the possible cause is another mod, but I don't want to do much because it is a difficult task to identify the cause mod.

Please help me, please.

 

Spawn new the pessima instead replace current (sometimes fix problems). If your game crash, your mod is broken and you should fix it.

 

I tried it, but it didn't work.

As a result of enabling only my mod and trying it, the usual phenomenon occurred after all.
As Agent_Y says, I think the mod I made is broken.
But I don't know what's broken in my mod, can you verify it?
Please see the contents of the transmission Jbeam below. Please.
