I recently bought a 07 Buick Lucerne CX. No check engine light when I initially bought it, of course they must've reset it, bc next day code popped up for shift solenoid B stuck on. It still drove decent but wouldn't go above 50mph. Once you hit 50mph it would just rev & rpm would max out, so I would just let of the gas until slowed below 50mph & it would engage again. Watched some YT vids & planned on replacing both shift Solenoids that weekend(it was gonna be all day event) as I needed vehicle to commute to & from work. It didn't make it to the weekend. Slowly lost drive gear all together, but would go in low 1 & 2. Then lost movement in ALL forward gears. Still goes in reverse. So I did more research, opened it up n replaced All the Solenoids(shift a & b, PCC), new wiring harness, new pump & was gonna replace the forward band, but it wasn't broken. Important to note there weren't any metal shavings in the pan, all the clutches, gears & friction plates were in good shape. Reassembled, but still no forward gears! The only code it has now is P2341secondary air injection flow or something, which is NON transmission related. So I'm hoping someone can gimme a list of ALL possible causes for no forward gears? That way I know what to check & double check, as I go along. You can hear & feel it shift into reverse, then Neutral, but when you go into Drive or below, you can't hear or feel anything. Someone suggested checking for a broken weld, so I'm taking it apart again & gonna post clips of my progress along the way. TY in advance for any help or advice given, I definitely need it.Unsure

They are MY videos of me showing my progress & asking for help or advice. Thought that's what you do here?? I'm not a mechanic, so idk all the proper or technical terms of everything. So I made short clips, bc a pic is worth 1000 words right?

I never looked at them. You can put them all into one post if they are yours.

Can someone tell me if these forward drum rollers are supposed to be more loose? They seem locked up...

We have one trans expert and his time is limited because he owns his own shop and helps when he can.

Hello,
No forward and good reverse is a broken forward band, could also hve a problem with the apply piston (rare) your problem is a broken 1-2 band. Sorry for late response, my shop is beyond busy. Gary
