T/C in,now tranny slips. I've installed a 2800 stall and made sure that they fluid level was correct.
Car feels great but when I stood on it it didn't want to go into third and the rev limiter was da da da da intil I let off. WTF? I did find out that my battery
is defective. Could the bad battery have an effect on the electronics managing the trans?

Sounds more like you need to have your shift point adjusted. Unless when you stand on it.. it goes stright to rev limiter it's not slipping. Just not shifting soon enough. A stall will change these characteristics.

Raising the rev limiter? Now I'll have to buy LS1 edit or a Predater.
Can this be adjusted any other way? If not then I'm screwed for awhile.
Hell I might even take the stall out and put the stock back in.

I wouldn't take it out. Maybe pay someone to do a limited edit. Turn TM off (which needs to be done) and raise rev limiter and adjust shift points. If nothing else get a HPPIII and just use it for the shift point adjustments. They go pretty cheap now.

How can I have a limited edit done?
Can a tranmission shop do this?

You would have to go to a shop that knows LS1edit.
I've seen pricing in the low 100's to get the computer work done for a convertor. Your in Ohio so it might be cheaper for you.

Thing is I don't have the cash right now for edit as I've got
6.0 heads in the shop. I was hoping not to tune until after the heads
are ready to go one in the next 2 months. Guess I won't be able to
see the improvements the T/C made alone.

I'd live with it till you get the Heads on. Don't waste money in between. Also what I did was pay for a full tune before I did my H/C. I talked to the tuner (business) and told them I needed some things changed to get me by till I got the H/C installed and they had no issues with doing these till the full tune. Might try it.

You need your shift points adjusted, along with the deletion of the TM, if you have a 2001 or 2002 model vehicle.
As suggested wait until you have your heads, and other engine work done, then get a complete dyno tune.

My car is a 2000. I'm unfamiliar with what the TM is and does.
If I have to wait until I do the H/C swap I'll change it back
cause I can't run the car the way it is and it may 2 months
before I have all the parts bolts, gaskets, pushrods.
Damn, if I only knew.

Search for what TM does. Or maybe someone will chime in and tell ya. Do what I did and go to where you are getting tuned. See if you can pay for a Full tune and get these things done now. As these are things they will have to do anyways. Most shops in TX will do this. Not sure of the ones around you.
Also are you installing it yourself? If not why pay someone to do that when you could just use that money for the edit?

I am doing the installs myself. However when it comes to tuning
the PCM I'll let someone else do that but educate me as we go.
I've been dying to drive the car as its been garaged all winter
and now it seems it may be most of the summer til after I can get her
tuned. I've gotta start playing the lotto.

What TM does is pull timing at the highest point of RPM when the car is ready to shift, if it reads too much line pressure. It is basically a safeguard for the stock transmission.
When you install a Transgo shift kit, it mechanically beefs up the transmission, and allows it to handle additional line pressure that the TC will create, however the PCM does not know you have the shift kit, it reads increased line pressure and then cuts the timing, this will equate into elongated shifts that are sloooooow.
The shift points of the stock converter that the pcm uses usually will not work in 2001 &2002 models, I am not sure how aggressive the TM is on 2000 model cars.
Before my dyno tune, I had trouble with idle hunting, stalling, and my personal favorite, locking and unlocking of the converter at freeway speeds. It would constantly shift between 3rd and 4th, and sometimes stay unlocked for the entire 30 min drive on the freeway.
Once my shift points were corrected on the dyno, and the TM deleted, the vehicle ran wonderfully. You will also lose HP with the converter change, however do not get hung up on numbers, it is how the vehicle drives.

Thanks for all the input. This really bums me out.
I had such high hopes with the T/C of improving
my 60'rs and et. I had no idea that I'd need tuning
with the 2800 stall. Guess I'll have to baby it around
until I get the means to tuning. Then I'll have to decide
what type of tuning. Oh well just my luck.

It seems like a big deal now, when I had the problems, it was monumental to me at the time, however after your dyno tune, all your problems will be gone, just find a reputable tuner that has experience with our vehicles.
You do not state what converter you have, however if it is a Vigilante 2800, your stall is actually at 3200 RPM. A friend of mine is having issues with his 2002 Z28 with the SLP 2600 stall, with his it is more the shift points than the TM.
Good luck
