Bongo Fury

Hi guys,
I was planning to do my ATF today but ran out of time with the other issues I had in another thread.

Quick question tho, I've read that it's a good idea to blow remaining oil through the pipes that lead to the cooler and have no idea where those pipes are likely to be...is it obvious once I've dropped the sump or can someone describe whereabouts I'll see them...I'm hoping I can plug a bicycle pump with a nozzle attachment into the respective pipe to push the oil through (worked a treat on the fuel pipes when I was back blowing into the tank the other day).

Also, is it possible to do this without raising the van ? looks like there's just enough room for me to slide under to remove the sump...I have a Pela to remove most of the fluid so hoping it's doable..

thanks,
Ant.

Just depends what you want to do .. a fluid change .. or a full fluid flush ..

You have to realise that there is more fluid retained in the touque converter than in the auto boxes sump .. so all the fluid is not changed by a simple fluid change .. only the fluid that is retained in the sump ..

You do a fluid change by getting the fluid from the sump either by removing the sump plug (as on my v6) .. sucking (part of it) out with a Pela pump .. or removing the sump (the best method of all as the filter / magnet can be cleaned at the same time) ..

As the return oil cooler pipe on the bottom of the rad need removing to do a full flush .. it requires two people .. because the engine needs to be running to pump new fluid through the system which mixes / flushes the old fluid out ..

So it is better with two people because when a measured amount of fluid is pumped out .. the guy in the cab stops the engine .. and feeds a similar aount of new fluid down the dipstick hole ..

The process contines until only nice new cherry red fluid is coming out of the oil cooler pipe ..

ahhh...that explains it..I hadn't appreciated that from the other threads I read. Thought you could put some air through the pipes to flush them through. I'll have to make do with the change and drop the sump....might then do it a second time in a few months to get a better new/old ratio..

thanks,
Ant.

You can blow low pressure air through the cooler pipes as they can get gobbed up with congealed fluid ..

Draining the sump .. refilling with fresh fluid .. using the motor for some time .. then draining the sump .. refilling with fresh fluid .. using the motor for some time again ...................

Repeated over time .. that will 'refresh' the old fluid with new ..

the 2 pipes are at the drivers side of the gearbox, they are short section of rubber to steel pipes that go forward to the front rad bottom(oil cooler).
see the lower 2 pipes in this link.

cheers guys,
I shall pucker up and try and put some air through the pipes to get a little extra out then...once my mate has dropped his high lift jack around as I can't get the bugger high enough with mine to get his axle stands under and although I recon I could just about drop the pan without jacking it, I'd spend hours faffing ...grrrrrr....

job done..thanks guys. Took me 2 hours including letting the filter dry out so I don't think I did too bad for a first timer. Fluid was surprisingly mucky compared to how it looked on the dip stick so it was due a change....might be placebo effect but feels like it's smoother between gears...nice...
Didn't blow through the pipes as I ran out of time really to crack a pipe off and it was beginning to get a bit messy !

1 stripped bolt found so we'll see how it holds up with the loctite gasket I used...

Point to note for other newbies....I was quite happy I managed to pela pump about 5 litres out through the dip tube. Once it stopped coming I gradually undid each bolt on the sump...not many drips so wasn't very messy dropped the sum and there was another litre in there..still not too messy.

Then came to the filter housing which removed nice and easily only to find a shed load of oil then pours out of it So...for those of you trying to stay clean...the filter housing has the big square hole in it...but it's at the opposite corner (drivers side front) where it fits into the transmission case (a circular spout on the concealed side of the housing fits snuggly into a circular hole in the transmission case by virtue of a rubber o-ring). Make sure you have a container underneath that corner when you pull the housing down and try to keep the housing level as you remove it (or slightly tilted so that the end with the square hole is elevated). I had a container underneath the rear edge of the transmission and the square hole as that's where it was still dripping from....result was a mess

Final job before the bash is to finish welding up my flat pack BBQ !
