The transmission fluid dipstick on a 1995 Pontiac Bonneville is typically located
on the passenger side of the engine compartment. However, it's *not* always easily visible. It might be tucked back near the firewall or under other components. Look for a dipstick with markings for "ADD" and "FULL". Sometimes it's marked with a transmission symbol.
It's important to note that some 1995 Bonnevilles may have an automatic transmission without a dipstick. In those cases, the fluid level needs to be checked by a mechanic using specialized equipment. If you can't readily locate a dipstick, it's best to consult your owner's manual or a qualified mechanic to avoid damaging the transmission.
