Sounds like you have a bad coolant temp sensor really common on those cars.Also inspect the connector going to it if the terminals are blue or green you need to replace the connector because its corroded.

i have a 2000 sl2 dohc saturn for about a month now. 150,000 miles. automatic. here is the problem. when we first bought the car it ran great. 2 weeks later, it started smoking out of the tail pipe really bad. took it to garage, said my catalyic converter was bad due to oil leakage. well figured out it was leaking oil down into where you put the spark plugs. well bought a new gasket seal kit, fixed that, new spark plugs and wires. there was enough oil in my spark plug holes to fill prob a quart n a half of oil though. well that got fixed. 2 days later i was driving and next thing i know it rev's up to 3500 rpms and wouldnt go down. found out i had a hole in my intake manifold. fixed that. NOW.... here is the new problem. the car starts great. runs great while its idleing. no engine noise or anything like that. Now... when you put the car in gear and start driving... you can go about a mile or so and it runs great.... once the car starts heating up... it starts jerking, shaking and the transmission will not shift gears. its like it goes into limp mode. but it only does it when the car is in gear and starts heating up. we were told it could be a bad coil pack... changed both of those and its still doing it... anyone have any insight????

I have never seen a bad coil cause the transmission to no shift.So when this happens does it feel like the transmission is taking off in second gear and never shifts from that gear?Also have you checked for codes in the computer?

after you get in it and put it in drive... you can go a mile to a mile n a half and it shifts fine... but as soon as the temp gauge starts going up... thats when the car starts shaking and sputtering. there is NO service engine light on... so it is not shooting any codes. thats the weird part. when it starts happening the car feels like its going into first gear and will go about 20 to 25 mph but wont go any faster and the transmission wont shift into any other gear. i hope this helps..... we thought it may be a transmission sensor.. but they say those will shoot a service engine code????? and mine is not

Please check for codes anyways even though the light isnt on.Also i would have a back pressure test done on the exhaust when its acting up.You could very well have a plugged cat.

It sounds to me like your injectors are leaking Drymmy.
   When you press the gas pedal all the way to the floor you shut down the injectors giving the motor a chance to clear itself out of excess fuel and then the vehicle starts.
In the am the car needs a little more fuel for a cold start but when its warm it needs a lot less fuel.
Check with Saturn or Chevy to see if there is a Tech service bulletin on that specific problem
