p1887 (TCC) issue on 97 Olds

Hello, new here, forgive me if I am a bit lost :)
1997
Oldsmobile
Cutlass
3.1L / 4T65E
202293 miles
I have code p1887 on a 97 Olds Cutlass (the Malibu clone Cutlass).
I understand that this code inhibits TCC functionality. I am having strange issues with slippage in all gears, intermittently. Sometimes the car runs just fine for a while, and then it will just randomly start slipping randomly in any of the gears. Occasionally I get a clunking when leaving a stop light (switching gears with a bit more force than normal but not terribly hard).
I have done some transmission and transaxle repairs / replacements in my time, but never on anything newer than early 90s, though I should have the aptitude to do this. Unfortunately, I do not have access to a lift. I have an extensive tool collection, a couple of hefty floor jacks and jack stands. I used to be a mechanic in the military and have a strong electro-mech background in the civilian world too. I read on another site that it would require some disassembly of the sub-frame to get at the issue (if it is the TCC switch), is this correct?
Any suggestions on how to go about this problem? What to look for first? Should I attempt it here at home?
Thanks in advance for any help with this issue.

I'm away from my data base right now so I can't look up the code.... I'm assuming it's not going into o/d....
The tcc issue shouldn't really cause your slipping problem so it sounds like you may need to do some internal work.
Whether you should do it or not is really up to you and if you have the right tools like pump pullers, clutch pack spring compressor and such then it shouldn't be a problem...
I believe the subframe does have to come out on that one... Those really aren't too bad to drop and once it's out everything is wide open... The only thing you have to do is support the engine from the top side. OTC makes a pretty nice support bar..... I've seen guys use a couple of 2x4s.... I have a 4' 1 1/2" pipe I use a cheater bar that worked perfect until I got the support tool............ Instead of chain I use ratcheting tie down straps, more precise and able to hold things a little tighter..........

Thanks a bunch Sidom.
It died on me on the way home one day so we are going to dolly it up to my cousin's pole barn (he has a lift) and take it from there.
Will let you know how it goes.

I'm glad we took it to my cousin's place. It would have been a nightmare to do here in my garage. We ended up just swapping the tranny out and she runs fine now.
We made an engine hangar from a couple of 4x4s and some chain.
The hardest part was getting the subframe back in correctly.
Thanks again Sidom!

Glad to hear you got it going Nolan.
I've seen & used that type of engine support....... works good huh....
You made a good choice picking a place with some room....
Hopefully there won't be a next time but if there is, it'll go way easier......
Thx 4 taking the time to post back the final outcome....

Hey again Sidom -- just a quick follow-up with a question. I let the car sit for a day and then took it out for a drive yesterday, and the transmission seemed to slip a bit until the car had warmed up for a couple of minutes. Any idea on that? I am getting no error codes.
Thanks.

I'm assuming you swapped it with a used tranny with isn't a problem....
I'm sure you did most of this but will mention it any way, when the other trans was installed, at the minimum it should've had a new filter and gasket put in it. Flushing the whole system would've been the best thing.
Even with all that you still could get the problem you are experiencing. It sound like some of the clutch pack seals are getting old & hard. When this happens you'll get some slipping when its cold. Once the seals warm up they expand and seal better.
There are some additives out there that might help with this problem. Some thing that will condition the seals a little more than just the tranny fluid. I really don't use much of those so can't really recommend any, maybe someone that's had some good luck with some will jump in..... I know years ago when I had a side job at a parts store we sold alot of TransX. I sort of look at those additives as a "cure or kill" type of thing.....
If it's just slipping slightly, it would probably be worth a shot, worse case scenario that transmission would have to come out anyway.
Hopefully you got some kind of warranty from where you got it and I know you already got the R&R down....

I'm with Sidom on snake oils - almost all of them. One of two perhaps I do like is what he mentioned - Trans-X
There's no "rebuild" in a bottle out there but the properties of this product can gently soften seals, dissolve varnish that causes stickiness in moving parts of ATF or power steering. It's use should be in conjunction with proper fluid and service and I suggest "sparingly" with anything you find.
It has clearly eliminated stickiness in power steering racks, shaft seal seepage in power steering. Untested in fixing transmission problems on my own or customers. IMO at some point a trans plain needs an overhaul. The key is "sparingly" and if tricks don't work don't go nuts but a repair is indicated,
