Where is gearbox filler plug on Lexus is200?

Answer 1

The Filler plug is a hex head plug about half way up the gearbox on the passengers side. The head is about 15/16s or 1inch drive. This plug will be hard to get off and should be removed BEFORE cracking the drain plug to change the gearbox oil in your IS200. The filler plug is closer to the flywheel than you might think (closer to the front) and can be removed using a shifter (there is enough space around the head of the plug).

The drain plug however is different. It's not the star head plug on the bottom of the transmission, (this contains a magnetic spring to catch debris), the drain plug is still on the side (passenger) of the gearbox and is the same size as the filler plug. This plug is surrounded by the design of the gearbox and you must use a socket to remove it.
