3 vehicles with bad PCS!

ooooh me want an SSEi, wanna trade?

But, the Casper's fan override kit for the GP,Regal, etc has successfully worked on one car here that I know of, a member named Rolm installed one, but I believe he has a 3.8, so Im not sure if the fan setup is different or not. I know the radiator, etc is so the fans very well may be.

I bought my 01 Intrigue in March when it was cold out and never had an issue. I've had the transmission fluid and filter changed before the scheduled 100k maintenance. I've got 97K on it now and noticed that after the first few hot days my trans starting shifting wierd (just like the TB's say). If I shut the car off for a few seconds the problem goes away. The problem is only intermittent.

Maybe the answer is as simple as keeping the fluid cooler?

Also, another thing we could try is adding a switch that allows us to turn on the cooling fans. I've got a 95 Bonneville SSEi that I've added a Aux fan over ride switch and that moves the heat out when I'm in standing traffic.

I think what happens is the PCS changes characteristics when heated up, whether the thinner fluid affects it or the actual PCS expands slightly like all things do in the heat, I dont know. What i do know is if my temp gauge never broke the 1/3 point my transmission would always shift perfectly...problem is most intrigues like to break the 1/2 point when sitting and it takes forever to cool back down (turning it off for 5 minutes seems to make it get hotter!) I see a nice spot down in front of the rad to get a cooler mounted, so I think I am going to do it as well. Should be able to get a cooler kit for $50...just a universal oil cooler. Comes with rubber hose, clamps etc. just cut one of the trans lines going into the rad, route it down through the new cooler, than back up to the other side of the cut line. Couple more quarts of fluid (plus the fluid lost from cutting the line) and your good to go. Saws-all should work ok for those lines...if not a pipe cutter should suffice...


The entire problem is basically the transmission doesnt have enough pressure to keep the shift points accurate, and if the pressure falls too low it will slip (like mine)..once the computer sees a few shifts that are outside the set paramiters, it will max out the line pressure so the trans wont slip and destroy itself. This essentially fixes the issue, but your left with very hard shifting and pump whining sometimes..and it resets after you turn the car off. So even though the PCS may still be faulty, if its only faulty in the hot conditions, cool it down and the problem should be much less noticable.
