Absolutely, a badly timed engine can run like a heap of S--t
if the timing belt becomes streched, it changes the relationship between the camshaft and crankshaft. Which will in turn effect the valve timing and engine performance. That is why many engines use automatic tensioners to prevent this from happening
Yes
The timing belt effects your camshaft timing, and in some engines your ignition timing (if the distributor or crank trigger runs off a pulley driven by your timing belt). Directly, your timing belt has no effect on your shifting. However, variances in camshaft timing will make your engine run differently and that MAY effect at what point the transmission shifts.

The population of Radical Performance Engines is 20.
All Saturn 4 cylinder engines have an internal timing chain. All Saturn V6 engines have a timing belt.
Pushrod engines have a chain. Overhead cam engines have a belt.
Some engines have timing belt, some timing chains, and some timing gears.
Most Jeep engines have a timing chain.
All Honda engines up to 2002 have a timing belt that must be replaced. Starting in 2003 the 4 cylinder in the Accord has a timing chain, but the V6 still has a timing belt.
