Pardon me for clarifying further.
Its just that I started experiencing the HardShift, or what the GM Mechanics call it as Shift Shock. They recommend that I replace the whole transmission, which is totally crazy. I told them i dont this the problem is the whole transmission just because they are lazy to look for the problem.
Well, anyway, our problem with our 2004 Chevrolet Venture (that according to most forums have this tranny as the standard model) started about 2 months ago when the following where done:
1) Re-installed the Thermostat by the Temperature sensor since this was removed 2 years ago.
2) Changed the ATF at 70,000KM, and the Transmission Filter.
They told me that the Venture normally does get the Hardshift/shiftshock after the ATF and filter gets replaced. They used, what i assumed to be a certified ATF brand.
Reading up on forums, i found that the shortterm solution would be to turn off the engine for about a minute. This method works for me everytime. BUt we do notice that the hardshift/shiftshock is happening more often than before.
We live in the Philippines, where the temperature averages at about 32C. The Temp guage would after read at the range of 90-92.5 to 100C on a hot day.
I am glad that there are forums such as these that exist for us GM consumers.
So I guess these are our problems:
Pressure Control Solenoid
Mass Airflow Sensor
That can be solved by NOT replacing the PCS and MAF sensor. But rather the installation of the 1 1.5 inch double stack 28,000 GVW cooler and the ZPP Shift Kit
May i ask for more info on the following?
What does the ZPP Shift Kit look like? Because there are the two things that came up from my browsing:

And may i also know how to install and where in the tranny do i connect the Cooler? TRANSMISSION COOLER, 28,000 GVW, NEW: eBay Motors (item 2453082364 end time Sep-02-10 16:17:27 PDT)
Im sorry for revisiting the questions. Its just that we are so frustrated with our Minivan already because we just recently had the Driveshaft replaced, and the left lower arm, because the lowearm broke off from its welding point, thus pulling out the CVjoint. Plus countless expensive repairs like the engine electrical harness, radiator fans and aircon compressor.
Thank you so much for your assistance.
