The 1988 Ford Festiva with a manual transmission
doesn't have a dipstick to check the transmission fluid level. Manual transmissions on these cars are typically filled for life and sealed. There's no routine check or topping-off procedure.
If you suspect a problem with your transmission (e.g., difficulty shifting, noises, leaks), you should take it to a mechanic for diagnosis. Attempting to check or add fluid where none is intended can cause damage.
