Transmission nearing the end?

So many of you know that my transmission has had a slip problem going into 2nd at higher RPM's. Well, some more things started to come up. Just started today leaving school, The car would sometimes have this lug feel where when accelerating in 1st gear, it would almost lose power for a second and then regain it and go on and not do it for awhile. Well, it did this about 3 or 4 times on my home from school. It also dropped into 1st from 2nd when not needed, like taking a turn and giving it almost no throttle, it went down into 1st. I drove it home carefully as I did not want to hurt anything else. I don't know if I was just driving int he wrong conditions and didn't really know what to do, or if it is dying. I've already added stop slip, MAP and MAF sensors are clean, throttle body is halfway clean, air filter could be changed, but I don't think it cause the lug. I'm not sure what to do. I was gonna drive it for another week and see if the problems subside, but if it turns out it needs a new tranny, I'm S.O.L. So are there any other things I could do to try and fix it? I was gonna try pounding on it and see if anything happens.

I should also add that I had my car scanned for engine and tranny codes yesterday and none came up.
 


don't flush it. just drop the pan . people have problems when they do a full flush.

Someone on here said all he did was a pan drop on 2 of his GP's and after, both of them slipped worse than before. Honestly, I'd take it to a GM dealer and have them do it. That way if something breaks, it's their fault.
 
Well it's been 2 days and it hasn't been acting up. It will still occasionally lug and do the power loss thing which I cannot figure out, but it doesn't do it as much. If I give it more gas, it helps haha. I will change the air filter soon and see what happens, it's pretty dirty.

If a trans is bad enough a pan drop alone could kill it. I've had it happen to me three different times on three different cars.
 
There is no way that dropping the pan to add 8.5 Qts of new trans fluid (I have been using Dexron VI for the last 100,000 miles) and filter will make the trans worse unless there is so much dirt/gunk in the old fluid that the new filter gets clogged quickly. If the fluid/filter has never been changed or has more than 80-100,000 miles on it, I would change the fluid/filter, drive it for a few hundred miles and change the fluid/filter again.

GM recommends changing the fluid/filter every 50K in heavy duty applications (city driving, hot temps 90+, police, taxi, mountain/hilly driving) or 100,000 miles for other driving (this interval is crazy and why so many 4T65E tranny's fail early). Lots of people never change the trans fluid...I have owned my GP since new and changed the fluid/filter at 40,000, 65,000, 90,000 miles and now after that every 20K...trans/engine has 180,000 miles now, shifting perfectly. I have no interest in replacing the tranny and have never had a tranny failure on any car in 35 years..At 90,000 miles I added (2) 18,000 GVW Double stack coolers in the grille which cools the tranny fluid outside of the radiator cooling which is totally by passed. Heat and dirt kill transmissions...minimize both and the trans will last a loooong time.
 
If the trans is slipping or showing signs of malfunction you are on borrowed time. You can install a shift kit, use additives, change fluid but you still face the inevitable, a rebuild. I say save your money, do nothing, and put your money towards a rebuild. Drive the trans till you can't stand it anymore then order a TEP trans. Everytime I have tried to keep a dying trans going a little longer by sinking money into it I have regretted it and ended up wasting money that could have been used for a rebuild.
