So what exactly will one of these shift kits do for me... Isn't it more of a performance mod? My car is completely stock and that'* not going to change. I'm not looking for throw-me-back-in-my-seat shifts, I'm looking for just the opposite. Positive, yet mostly-undetectable shifts. Will a shift kit help me?

Also, I've been reading that a shift kit for the 4T65E can actually extend its life... How? You'd think that it would decrease the life of your transmission.

Everyone here keeps mentioning these shift kits like they're the miracle fix... Is this true or am I just cynical?

Installing a shift kit cleans up the shift accumulator, new o rings if needed, and shortens the shift time. Buy doing this the bands grab faster so they wear less. That'* why the trans lasts longer. It'* not going to shift harder, just faster.

Aha. I see. Is there a "better" company to go with when getting the shift kit. I see Transgo has one, price is right and they seem to be a good company. Are there better choices out there?

They make a good kit, so does Intense racing. Bill and I are also making up shift kits that are as easy as they come. Just swap out the accumulator and that'* it. Bill has 3 made up, and I'm making one up this week.

I took on the task of siphoning out some of the tranny fluid to get back to the right level. It turns out I was a bit over 1 1/2 Quarts overfull. (the fluid was also quite dark from the Trans Tune doing it'* job) After driving the car since, I have noticed that the shifts when cold are smoother, but when the tranny is hot, I (sometimes) get the same harsh engagement into 3rd, 4th and when the TCC engages. If the problem is still there after I drain and refill (with a new filter) with Dexron IV, what'* the next step?

Is there any way to trick the PCM into thinking the tranny is cold? My shifts are perfect when the tranny is cold... (Or is it just because of the hot fluid/components that'* causing my harsh shifts?) Could it be a solenoid problem or maybe valve body problem?

I did notice, however, that I am getting small bubbles on my dipstick when I check the level... After highway driving today (70mph), I checked the fluid when I pulled in the driveway and I had about 4 tiny air bubbles on the dipstick...?

Bubbles on the dipstick indicate too much fluid is still in the transmission. Remember, you have to be on a level surface when checking the fluid levels.

When I took out the 1.5 quarts, I had just filled up the container I was using at the time so I checked the fluid (I was about 1/4" past the top of the cross hatched area) and called it "close enough". I guess even that small amount of fluid can cause foaming... I'll have to siphon some more out tomorrow...
