Idk if this is all related but i wanna give u all the info. yesterday i noticed coolant and oil low so i filled them and within 10mins there were 2 very small drops of oil in the middle of the engine back by the firewall. couldnt check again for 2 hrs but then there was a small puddle of coolant close to the firewall as well but closer to pass side. started but seems like idle is low. a few wks ago it felt like the tranny slipped and shifts hard and shutters. went up some mountains and it had a really hard time but thought it was cuz of high elevation. sometimes when i put the gas pedal to the floor it takes like 4 seconds b4 it goes. no warning lights on the dash. the check engine light comes on (not very often) and the defrost vents r the only ones that work no matter what i do to the controls. noticed the vacuum hose was disconnected so i fixed it and it was good for a while. sometimes it'll do it again but the hose will b connected and the check engine light on. if i restart the car a few times it fixes itself and check engine goes off. replaced water pump and tensioner oct 2013. Has 149,000 miles. please help!!
You need to have the cooling system pressure tested. This will tell you what and where the leaks are. The oil leaks are probably due to age of gaskets and seals. With age comes issues with vacuum lines too.
ok thanks. would that b the reason the tranny seems to have problems too?
Generally speaking no. Vacuum modulators on transmissions are not something that is common anymore.
I tried to upload 2 pics but it says theyre too big. what could b making the tranny act like this

Try disconnecting the electrical connector at the transmission and see if it stall when you put it in gear. You will get a service engine light, but not to worry, it will go back out once you reconnect.
By disconnecting the wire connector we can tell if it is transmission related.
Good luck, let me know.

SOURCE: transmission shifts hard when the trac off light comes on
youll need to scan for transmission codes. the trac off light is a default of the trans going into a default safety mode. Bad speed sensors and simple little bolt on items like that can cause the condition but only way to really nail it is with a computer.

Check the fluid level and make sure it is up.If o/k then suggest a trans service which will have the filter and fluid changed. This could be your problem.
SOURCE: 2002 Alero shifting hard
I have a 1999 Oldsmobile Alero and my car was running rough and stalling. Also when the car was shifting, it was making a "thud" sound. My service engine light was on, so I took it to Autozone to run their diagnostic tool. It came back with code P0108 and they advised me to check my vacuum hoses as a possible solution. I looked and found that my air hose running from my throttle body to my map sensor was disconnected. I reconnected the hose and the engine ran normally and didn't make any "thud" sound when shifting. My car is back to normal. So check your hoses. If its still running rough, you may need to replace your map sensor.
