Full synthetic fluid (oil) may benefit some applications by lowering operating temperature resulting in a longer life, but not all transmissions can use the synthetic fluid. Check with Aspley Automatics for their advice on your specific application and needs.
Always check the fluid level with the engine running with the transmission in PARK and with the engine at operating temperature. Remove the dipstick and wipe with a rag. Insert the stick fully and remove. Look at both sides of the stick to verify the same indication on each side. Repeat the process 2 or 3 times.
The reason to check both sides of the dipstick is that after the fluid circulates through the transmission, it dumps back into the pan area and will creates an uneven level and some fluid will "slosh" onto one side of the dip stick and give a false reading. Some transmissions are worse than others.
Also, the difference of fluid temperature will affect the measurement. The fluid volume expands when heated to operating temperature.
If you have added transmission fluid, go through the same procedure, but repeat the process several times before you look for a reading. Some will give a false reading.
If the fluid level is low, you have a leak! Transmissions do not consume fluid. Have the leak diagnosed and repaired by Aspley Automatics ASAP to prevent more serious problems.
