GEARBOX SERVICE

1

The gearbox service requires its automatic transmission fluid (ATF) to be drained before the sump pan is removed and the filter inside replaced. Using a 14mm socket, Rob removed the drain plug and collected the ATF. The gearbox holds up to 10 litres. 2

Once the old ATF had drained, Rob used a 13mm socket to progressively slacken the 13 bolts which secure the sump pan to the gearbox. These were not very tight, so once all of them had been slackened, they could be wound out by hand. 3

The messiest part of the job comes when the sump pan is released. Rob braced himself for an ATF shower, but managed to avoid most of the drips. Unfortunately his drain bowl missed most of them as well – he was later seen mopping up! 4

The gearbox’s filter is loosely secured to the base of the gearbox with a 13mm bolt. Once undone, Rob discovered that there’s more ATF inside a plastic connecting pipe. This pipe needed to be extracted to replace its O- ring. 5

A rubber gasket had been fitted to the sump pan, which needed to be peeled off and discarded (our new gasket is a paper type). The mating surface on the sump pan and gearbox were both thoroughly cleaned prior to reassembly. 6

The plastic pipe was refitted with a new O- ring, followed by a new filter. The pipe needed to be pushed up into position and the filter waggled a little to force the bottom of the pipe through a seal in the filter, then it was secured with the 13mm bolt.
