1999 Chevy Monte Carlo
I'm looking to replace my transmission in my 1999 Chevy Monte Carlo and was wondering if I could use one from a 98 or if anything has changed between those years

The 1999 Monte Carlo was available as an LS or the more race-car-minded Z34. The base engine on the LS remained a 3.1-liter, 160-horsepower V6, and the Z34 kept its powerful yet fuel-efficient 3.8-liter, 200-horsepower V6. Mileage for the LS is 20/29 city/highway, while owners of the Z34 can expect 19/30.
Drivers love the comfort of the vehicle, yet complain about the quality of the brakes and the time needed to go from 0 to 60, even in the powerful Z34. Tuning these cars for more power can be difficult, as the engine compartment is relatively small and tightly-packed.

My friend saw my oil light on so he put oil in my car for me but he bought 10w30 and my car needs 5w30.
Chevy Monte Carlo that cranks but won't stay running. I recently changed the fuel pump & fuel filter. I check the pressure pin on the injectors, the fuel pressure regulator, cleaned the MAF but didn't change the sensor, cleaned the the throttle sensor also. Only way it stays running is if I use starter fluid and I'm not using much of it at a time because I don't want to mess anything else up from doing so. Does anyone a clue what could be the reason for my problem????
I have a 99 montecarlo with a blown 3.4 and a 98 Buick lesabre with a 3.8, will the motor from the buick bolt up to the motecarlo?
1999 Monte Carlo I bought with 103K miles and drove 15K pleasurable miles in 6 months with regular oil changes and fluid checks. Coolant began to leak within in 3 miles of my home, temp was okay and then started to overheat slightly above normal as I arrived home, car puttered once as I pulled into driveway. I let the car rest a couple days, topped off with proper amount of coolant, but engine would not crank (only once did it spin for a second or two. Had battery checked, it's fine. Are the pistons having a tough time? Gasket? Manifold? thanks
