If you like go ahead and let someone sell and replace your transmission but here is my suggestion! Check around and see if you can find a minor vacuum leak! This can simply be the big round hose that goes from the fuel injection to the power brake hub! This is normally a push in connector which has about a 1/2 inch hose clamped on it! If there is any kink or the connector is not in correctly a leak will occur and the transmission will shift rough as though you will be thrown out of the vehicle! Try unplugging this connector and plug it back in hard and straight and maybe you will be lucky and fix your problem. If the vacuum is correct your transmission will shift better than you have ever experienced!

The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.

Oil loss and code 1806 on my 2001 cadillac el dorado

i believe what you mean is a P1860 code? There is no P1806. The code is for a torque converter clutch pulse width solenoid, which is an internal electrical part of the transmission, it is a pretty labor intensive job, and you could actually end up needing a full transmission. that and the oil pan gasket could lead to a heafty bill, if its worth it to fix is up to your and your financial situation really, ask yourself if you can buy a different car with the money that you are quoted for the work.
