Could be the catalytic converter clogged-up -check the exhaust system for restriction by doing a backpressure test

If it is a clogged catalytic converter would there be smoke comming from the exhaust because there isnt it mostly smokes from the engine?

Check the exhaust system for restriction disconnect the exhaust pipe from the exhaust manifold and see what happens and then comeback with some results

Check all the cylinders if it has water/coolant -you sounded as coolant is burning in the combustion chamber-sweet smell

If its leaking its causing the transmission to slip due to low fluid-get it fix
