A faulty transmission and one that’s just low on fluid share many of the same symptoms! If your vehicle hesitates when your automatic transmission shifts gears, check the transmission fluid level you let any mechanic start talking about servicing or adjusting your transmission or selling you a new one. Obviously, adding transmission fluid is a lot cheaper than replacing the whole transmission system!
Since 1996, STREET RODDER magazine has built a new car every year and then turned Jerry Dixey loose on an unsuspecting nation to travel the highways and byways of the country to promote the hobby we all love. With all the miles covered we’ve learned a number of lessons concerning the construction of a safe, reliable car, and with the record of performance that’s been established we’d classify the endeavor as an unqualified success. This year’s car, a reproduction ’40 Ford coupe being built by Hollywood Hot Rods, will be equipped with an automatic transmission from Gearstar.
If your vehicle hesitates when your automatic transmission shifts gears, check the transmission fluid level you let any mechanic start talking about servicing or adjusting your transmission or selling you a new one. To check your automatic transmission fluid, look for a dipstick handle sticking out of your transmission. This is located toward the rear of an in-line engine on vehicles with rear-wheel drive as shown here:
How the transmission shifts compared to normal is another way you can tell if something is going wrong in your automatic transmission. An automatic transmission shifts gears by changing which of the planetary gears are moving, held stationary or coupled to the input or output shafts. These changes are made by a series of clutches and bands and are activated by pressure changes of the transmission fluid. As these clutches and bands wear out it can cause your shifts to feel sloppy, take longer or even have the engine over rev. The wear of these clutches and bands is accelerated by having dirty transmission fluid circulating cause excessive wear and premature failure. In this case, a transmission rebuild is the only thing that can solve the problem.
