Odd (or maybe not) transmission condition

Alright, so I had to move one of my SVXes to get it to where I have access to work on it and was told originally it had a bad trans and I assumed high clutch/brake band failure or one of the two, but it seems to be neither. The transmission has Reverse, 1st, 3rd and 4th gears, and lockup works as it should. The transmission never seems to make an attempt to even get into 2nd gear at all. Eventually, the revs get high enough and it eventually just goes straight into 3rd. Any ideas?
Any specific questions, feel free to ask and I'll explain anything better.
I don't need this transmission that is in the car to work properly but just trying to learn/ get an explanation.

Re: Odd (or maybe not) transmission condition

That is weird.

If there's a high clutch, then there must also be a low clutch right? Maybe the low clutch is trashed instead of the high clutch?

Idk anything about autos...

Yeah, my current thought process is,

1st gear is the low/forward clutch
2nd gear is forward clutch+brake band
3rd gear is high clutch
4th gear is high clutch+brake band

So that eliminates the brake band. I was under the impression that the transmission uses the forward clutch for 1st gear unless the gear selector is put in the "1" position, then will use the low clutch. However, my memory is really, really fuzzy on this at the moment.

Re: Odd (or maybe not) transmission condition

As Dave says, what happens if you put it in 2nd and press the manual button. Will it take off in 2nd?

Oops, I hadn't seen Dave's post. I tried putting it in 2 and pressing the man button after moving but not from a stop. I will try this tomorrow.
As I said, it's more of a curiosity thing than anything, but I will report back.

Re: Odd (or maybe not) transmission condition

Alright, sorry for the delay, but I was finally able to test things out. By all means, it appears to not want to go into 2nd gear, but all other gears operate fine.
With the gear selector in "2" and manual depressed, it seems to rev (slightly, with only a slight raise in RPM's under light throttle), then hear a slight noise from the transmission and it still is in 1st gear. It does the same if selected in "3" and manual mode depressed. As stated, 3rd and 4th gears operate as normal with torque converter lockup working as it should.

Is it just me or are all signs pointing to a "stuck" solenoid or faulty solenoid? there is no transmission code.
