Did you see any of my posts concerning the 4T65E in my 2005 Buick? I did the shift kit install, made little difference. I then decided to install a new Pressure control solenoid, no difference. I had the car scanned twice, no codes. I talked to Dave at Triple edge, He said I need a new/reman transmission. Be sure it has all the updated/upgraded parts.
Currently I am driving the car gingerly while I order a new/reman transmission.

Unfortunately the shift kit will not "fix" all units especially when there is a problem that is not accumulator pressure related.
It is a good preventive maintenance mod and does work on some units that are having long shift time errors.

IMHO its a cheap place to start before going deeper into the unit and one of the few things the average DIY can do at home.
Generally if it doesn't work its going to be something serious and beyond most DIY.

How many miles on your transmission Tzu? It just maybe time. May not be worth it though. Drive this thing until it stops or is no longer safe.

Mine started acting up at around 70,000 miles. I wish it had just imploded one morning. Then I could have installed a new/upgraded transmission along time ago.

It has 228,000 miles on it right now. I used it all winter and no issues. I thought it was engine related because if I am at a drive thru waiting in drive with my foot on the brake, the car will sometimes stumble for a second and then catch itself. On the highway with everything warmed up doing 55 in OD, the car will seem like I turned off the ignition switch and then turned it back on again in 1/2 second. I would think the trans. is in it's high gear with no more pressure shifts? This morning I started it up cold in park, ran 30 seconds still in park and stumbled like it was about to stall, but then idled fine afterwards until 10 minutes into the drive where it would surge again about 4 times. Would a defective MAF sensor cause engine/trans. shifting to be erratic? That is a $150 part to gamble on again. Average gas mileage went from 25mpg to now 23mpg.

Scan for codes. Generic and enhanced.

Don't replace any parts solely on my input, but yes, a MAF sensor can cause the driveability issues and shifting issues.

One guy I do work for has an 02 Tahoe that would shift all sorts of mushy into 3rd (IIRC)- especially when you're hard on the throttle. The few times preceding the fix, I would do something unrelated to the MAF and test drive it and set a code. The first time, I cleaned it and told him to keep an eye on it. The heck of it was that it would never code for the owner. Whenever I did any work to it, it would code. Turns out I drove it hard enough to kick the code for "MAF out of range" Finally convinced him to replace it and BAM! Trans shifted perfectly and no more MAF code.

As a test, you can unhook the MAF. The computer will default to a predetermined value based on engine speed, TPS and MAP. The computer will always have the predetermined value, but the MAF will report back the actual. If the MAF varies too much from the computer's idea, then there is usually a code. But not always.

Yeah, PCMs seem to try too hard to believe a faulty sensor. When I installed the wideband in my '04, I used a factory O2 hole and removed the original O2. I just tied it up out of the way. It would go to about 10:1 AFR at idle on that bank trying to get that O2 to switch before it would give up. There was an audible change in the engine noise when it finally set a code and went to the tables.
