check vacuum hoses, pcv valve etc. it seem this is not electrical related, it is more of air exchange if my term is correct, example is the hose from engine to air filter and so on check everything cuts,kinks, rubber tend to crack at age, or when soaked in oil this sort of thing.

You could possibly have a bad heater control valve if the car has one. Another item maybe a stuck or faulty blend air door. This would be the actuator most likely. It may not be shutting off all the way to allow complete heat through. The other possibility is a partially clogged heater core.

All years are same 1992 to 2002.

saturn was never the best model of car sold! amazed it has lasted this long. sounds like a re-build (not worth it)- possibly a 're-built' replacement. labor would prob. cost more than tranny! prob. need axles & bearings replaced as well. part it out and get a newer compact ford, or toyota product!! good luck!

not enough info sorry

p1811 means=Replace Pressure Control Solenoid Valve Assembly. Its a common problem with saturn transmissions.

What kind of transmission ?

The first thing that comes to my mind is "45 MPH"... and let me explain why..... Your engine you said is running GREAT so a MPH is not going to effect the running of the Car but what happens @ 45 MPH you ask?Your Torque Converter goes into Lock up.... If the Torque Converter is slipping in and out of lock up, you are going to have an irregular pulsating of the engine playing catch up.you need to do this, try and drive the vehicle (you did not say what kind of vehicle it is), and drive it without the OVERDRIVE On...So drive it and see if it is RPM RELATED. If there is no CHUG and you can go all the way to 55-60 without issue, Slow down below 45 and put the OD IN and accellerate and see what happens.. Is the Problem SPEED RELATED? Is it RPM Related?If it does not happen with it OUT of OD, then what you probably have is a Torque Converter Failing... I hope this helps
