I hear a click sound under the hood
I have had numerous opinions from transmission repair shops, independent auto repair mechanics, and even gm mechanics. The question is if you have a automatic transmission that hasn't been serviced on schedule (fluid and screen change) and it is getting up on miles (say 150,000), should you service the transmission, changing the fluid and screen? Some say that you will initiate a transmission failure because the transmission is now working because of clutch wear material actually filling in places to keep the transmission working, and new fluid would loosen those causing slippage and then clutch failure. Others say that its always correct to service back to good /new fluid and new screen and you will not cause any problems and actually lengthen the tranny's life because its now properly lubed and supplied with good fluid ?? I can buy both arguments but am curious if there is any real validity to the first idea - my gut is to service the transmission screen and do a half fluid change out so that its improved but still leaves some wear material in the circulating fluid.???
Thoughts....

Pin will not release
This has only happened while driving at high altitude in the Rocky Mtns. The instrument cluster lights go out and gauges go down before it happens. The car kind of chugs along slowing down then gaining some speed, losing and gaining until we just pull over or it stops. We've been able to roll to the side of the road to stop safely. After car rests 5 minutes, it starts again.
The air blows out just fine. I've had the compressor replaced and had the system recharged. However the air is still not cold. The shop told me they would charge $80 an hour to try and determine what is wrong with it. Wasn't too comfortable paying that amount of money, especially after they told me that it was the compressor and I paid them to change it, and that wasn't it. Any advice or help would be greatly appreciated.
every time i started my truck during afternoon like 2:30 pm. in my indicator pop out that my air bag needs service. i acknowledge it by checking on it. in the morning it doesnt appear the error. we tried to re-setted in the shop of my friend with a code of A1 i think. but when i started again it display again. tried to move my driver set back and fort and the display dis-appeared. im planning to bring in the dealer next week for diagnostic. any idea and why having this intermittent error i have with my truck
Seems to go rhythmically To sounwaa exhaust, kind of a wa wa wa sound. We changed water pump and was wrong, can't really afford to keep guessing. Drives great, ac works, still makes sound when ac is off Any advice would be great
