Draining gearbox

Hi All. Just a thought, and probably daft, but if you want to drain the auto box and don't have a Pela pump handy, could you get anywhere by disconnecting one of the pipes from the cooler? Especially if the van was nose down?

Have you checked if you have a sump plug .. some do ..??

The more efficient way to flush out the gearbox .. and .. the toque converter is to dis connect an oil cooler pipe at the bottom of the radiator .. with the HAND BRAKE HARD ON and box in 'P'ark ..

Place a measured container under the open end (say a 2 litre + plastic milk carton) ..

Second person starts the engine ... you tell him to stop the engine when (say) 2 litres of fluid is pumped out ..

Topped up with Two litres of fresh Dexron 3 down the dip stick tube ..

Engine is re started ... you tell him to stop the engine when (say) another 2 litres of fluid is pumped out ..

Topped up with another two litres of fresh Dexron 3 down the dip stick tube ..

Carry on until only fresh / clear / red Dexron3 is getting pumped out .. reconnect the oil cooler pipe .. with the HAND BRAKE HARD ON and box in 'P'ark .. check the fluid level when hot and with the engine running ..

I wouldn't rely just on the handbrake. Make sure the wheels are thoroughly chocked. Dextron isn't especially cheap and there'll be some waste and the opportunity to clean the autobox and filter/magnet will be missed of course.

I can recommend a Pela. Had one as long as i've had my Bongo and its done all my oil changes. Just need to be a bit careful not to snag the probe when putting it down the oil filler hole.

Good point on chocking the wheels as well as being in 'P'ark and the hand brake hard on ..!!

I used this £10 pump. Had to cobble an extra pipe to fit down the dipstick shaft. It did the job just, bit leaky and messy but you get what you pay for. Lot easier if oil warmed up.

My son as a Smart car (with not so smart engine sump without a drain plug) ..

We used a lecky pump similar to this to do oil changes ..(Similar ones are some times for sale at Lidle / Aldi)

A treat for the future! I've just done an oil change.

Another vote for the Pela, expensive but does make everything cleaner and easier. In the winter you can do oil changes from above without having to roll about on the floor getting wet and cold.
