Auto Trans Service Diy

[Factory 5]

Hey all,

Just thought to share a brief run-down on what I did with my auto. Sure there are some other better things to do, but this got me out of trouble, and perhaps another newbie out there needs the same help.

I got a 4N71b transmission filter kit from Repco, will get part number later.

I also go 2x 4 litre containers of Dextron III (the Penrite one was on special for $32 each at Autobarns on the weekend)

Car was warmed up, jacked it up and put on axle stands. (Needed to be higher though. MUCH higher.

i got some little g-clamps and clamed the sump to the trans.

Undid all the 10mm bolts around the trans sump.

put my BIG catch tray underneath to take at least 7 litres

then off came the clamps, and woosh.... stinky brown trans fluid everywhere. (including my left eye... )

I should of let it run out slowly.

anyway while that was dripping away, I did an oil change.

Then there are a seriee of 8mm bolts around the filter tray, undid them, then 3 10mm bolts, and 1x 10mm nut. (which was pretty tight)

let all that drip away.

Then to clean out the trans fluid cooler and lines, I figured out which direction it all went ages ago, disconnect the lines and flush though with air (i just had a bike pump)

same with the lines to the trans, all the goopy crap is all gorn.

Install the new filter tray, dont do the bolts up mega tight, (as oulined in the service manual)

The 10mm ones are a bit tighter, then the 10mm nut, tight.

Degreased the sump pan, came up nicely,

On goes the new cork gasket and then the sump.

Then the 10mm bolts all round. i did them reasonably tight, left for an hour (to finishe the oil change) and re-tighten, the cork compresses a little bit over time.

Then loaded up my hose and funnel, and refilled 5 litres first up, started the engine and cycled through all the gears nice and smoothly.

Then let it sit and check levels.

The manual says 7 litres, and apparently 2 litres of that will stay in the torque convertor. It miixes up with the new fluid and what not, no huge deal.

took it out for a spin (at 2am thismorning, so no traffic! niiiice)

The difference was AMAZING. no more huge flare ups between changes, more solid changes, overdrive is more decisive (still need to replace the o-ring around the solenoid)

All up it cost about $90, so worth it.

Hi,

Thanks for the useful write-up. Sounds like a messy job though, is there another way to drain fluid before removing the pan?

This eBay seller has VL service kits: http://myworld.ebay.com.au/rossb7/ ($24.50 + $12.00 postage)

What does Repco sell them for?

cheers,
