Checking the autobox

I am considering purchasing a used Honda Accord 1.8 automatic and would appreciate your advice on checking the autobox for faults. In the April 2013 issue of CM there was a detailed article regarding various autoboxes, but this back issue is no longer available.

Also, what could I expect in MPG?

The first check you should undertake is to confirm the condition of the gearbox fluid. If this is dark or smells burnt then it normally indicates gearbox problems. The CVT gearbox fitted to the Honda had one major failure point: the starter clutch pack. This should allow a smooth take-off before the forward (or reverse) clutch packs come into action. This failure is easily checked by driving away from a standstill slowly and feeling for any juddering or jolting. Providing the drive from standstill is smooth, the rest of the gearbox is usually OK.

Due to the nature of the constantly variable transmission, it is often difficult to know if anything is slipping during normal driving as the engine speed will rise when approaching an incline. This is a normal characteristic of the 'box.

The biggest drawback with the Honda autobox is that the unit is very expensive. A new one retails for around £8000 and a fully rebuilt one will cost around £3000.

With regards to the MPG, a vehicle built between 1998-2003 should average 31mpg in normal driving conditions.
