At my wits' end with this trans...

I don't blame you. I swore when I got the last bolts tightened on the trans this time around that if I had another god damn problem with it, I'd be going straight to a stock 4T80. I thought I'd at least get a season out of it before it broke though.
For Saturday, just make sure your HPT is handy and repeat this as necessary in between passes
LOL!!! I was fully prepared to do that until it just stopped moving in OD/D.
That'll be one of my tests tomorrow to see what happens when it hits 3rd. Not expecting positive results.
IIRC Dropping it in 1 and 2 uses a different apply (read not the forward band used in 1st gear in D mode) than 3 and D.... So you will get different results. This is why manually shifting isn't a good idea. This is also why a forward band failure causes 3 and D to fall out, but 1 and 2 will still work.
P.S. (Also IIRC) The forward band that fails is used only in first gear, so going manual 2 to the "3" on the shifter should result in 3rd gear, until you slow down enough for 1st to try and engage.

The fact that it's a 97 is irrelevant. The only solenoid replaced is the TCC and the correct valve body is attached. Solenoids (and PWM) and valve body are the primary non-compatible elements and it's got the right ones in it.
I'm going to try getting to third with manual shifting tonight to see what happens. If it works, I'm gonna go to GLD and thrash the piss out of it anyways. What's not a good idea about manual shifting???
If your just cruising, it's fine, but if your racing it, you go from max line pressure on manual 2nd to standard line pressure in 3rd, the computer doesn't automatically know that's what you did, it has a delay while figuring out what gear to go in that causes a bigger than normal Rev up durring the shift. Then as it is engaging, this causes a shock load on the trans (like when the tires suddenly grab after a burnout) . You may be fine with the upgraded hard parts, but just something to be aware of.
I've also heard stories of it going back into 2nd and bouncing off the limiter before shifting to 3rd, so it may be a slow run, and make sure to your limiter is set properly.
Thanks for the extra information. The test drive yesterday went much better than expected and the manual shift from 2nd to 3rd was strong and crisp with no lag. I didn't WOT it, but normal driving went ok. I was kinda surprised. I found that it would not actually ever go into 1st however. The trans range switch recognized 1st gear as selected, but there was no shift when the shifter moved to 2nd and the scanner showed 2nd. So, mostly due to that, it's getting parked and ripped apart again.
Mike Dye? Or the other dude that took over?
I forget, was the 97 trans vacuum controlled, or was that just the GT?
Mike Dye left me out to dry. The other dude was Ray who was mostly just slanging business for that hack Mike.
All the GPs were 4T65E as far as I know. I don't think there were any vacuum controlled transmissions in the GP starting in at least 97.
Yeah Miker left a few people out to dry. Sucks to hear though.
THe 97 GTs and SEs that were NA 3.8 powered used the 4T60E instead of the 65, and those were vac controlled. They made that change in 98 and moved them to the 4T65E. I checked after I made that post. My bad. Sorry for the confusion.
