I have yet to find a vehicle that is experiencing transmission problems other than my own, but the only thing I can narrow down is that my vehicles use non-default values in the engoptions line.

It seems as though clutchtime, shifttime, and/or postshifttime is not working like it should. It takes my transmissions multiple seconds to change gears now.
In 0.4.5.1 my shifts were quick, now they take forever, so something has changed.

Please test again when the next nightly build is out. This might have already been fixed.

Tested through build 36 (Feb. 7). Behavior is still present, however, I identified another vehicle impacted:
OnyxPL's Audi 80 also is suffering from the very slow and mushy auto trans.

It also uses non-default engoption values:
engoption
;inertia, type, clutchforce, shifttime, clutchtime, postshifttime
0.05, c, 320.0, 0.30, 0.40, 0.30

Here are my values, which are also non-default and causing the same behavior:
engoption
;inertia, type, clutchforce, shifttime, clutchtime, postshifttime
2.5, t, 3000.0, 0.40, 0.42, 0.01

Additionally, stallRPM, idleRPM, maxIdleMixture, and minIdleMixture behave differently than 0.4.5.1.

I can't reproduce it, sorry.

All of these work just fine for me:

I've also verified that the Engoption section is parsed correctly.

Here's a video of the behavior on my HDX:
(Tested in Build 35)
https://youtu.be/IjcUMIooylY

Pay attention to both the speedo and tacho needles.
My finger was firmly planted on the up arrow the entire time.

First of all, great video!

But, in both cases it takes ~20 seconds to reach 50 km/h.
And in both cases it takes ~13 seconds to reach the 4th gear.

The only difference I can see, is the time it takes for the clutch to be fully released.

What exactly do you mean when you say "mushy and slow"?

I would really like to improve it, but I am not sure what exactly you dislike about the current version.

Do you only mind that the engine speed is not decreasing as much as it used to do, during shifting, or is it something else?

Edit1: I have to admit, the clutch release is not ideal. I'll think about a solution

Edit2: You are right, it was slipping the clutch way too long.

@graysonk95 please give this a try: #768
