Happy Christmas

Having read the necessary PDF files in the members area, it appears that if you do not have the appropriate pump you have to drop the sump of the automatic transmission to get the ATF fluid out

This begs two questions:

#1 prior to refitting the sump, has anyone ever brazed a sump nut and threaded insert actually into it? If you shouldn't, why shouldn't you?

#2 can you use a drill pump (google: Draper 18937 Drill-Powered Pump for an example) to get it out? if not why can't you.....

Questions, questions, questions

Hi
1/. The same thought crossed my mind
2/. I bought an electric 12v. pump designed specifically for the purpose
HOWEVER...
Laziness, cold weather and disability prevailed, and I got the local garage mechanic to dirty his fingers for £10.00

For a fluid change you might do every 50k miles, is it worth the effort brazing in a sump plug. And anyway, you have the opportunity to clean everything up in there when you remove the cover, and this is a major consideration. Use a pela pump to suck out the majority, plus use it for painless oil changes. No dirty hands or dirt of any kind permissible of course when dealing with the innards of the autobox

There is a large magnet inside the sump and a mesh filter filter. The only way to clean these is to drop the sump off, and as it only needs doing once every 50,000 km it's worth doing properly.

Having a Pela pump will make the job less messy as you will able to get the majority of the ATF out first, although as long as you have a suitable tray you can just slacken off the sump bolts and the catch the fluid as it runs out. You could potentially knock something up with an electric drill powered pump if you could find a suitably thin pipe to fit down inside the dipstick tube.

I would think that, with the small bore tube needed to drain the ATF, there would be insufficient flow for a drill pump to raise the fluid fast enough to work - they are designed to be used with a half inch hosepipe.

All things being equal I will drop the Auto-box sump and take the opportunity to clean the gubbins inside, has anyone successfully produced a photographic record of the process once the sump is removed. as I for one have read the textural description and there is:

"Remove the filter from the mount inside transmission; this is accessible when
pan is removed. Clean filter and re-install"

How big is the filter? how is it secured, bayonet? (etc etc)

If there is nothing to provide a photographic record of the process then lo unto you, I shall deliver it upon thee

Miss fixit did it a few years back. Plenty of pictures in this post.

I popped into my local Auto gear box specialist recently .. (all they do is auto boxes no engine or general car repairs) ..

A fluid change on my Bongo would be £60 (+vat @20%) .. I assume that was a simple 'suck out of the dipstick tube' job ... when I asked how much for a full sump off service including filters .. nipping up the bands etc:, that price 'shot up' to £150 (+vat @20%)...!!

as far as im aware there are several different gearboxes and filters so dont panic if yours looks slightly different.
the one shown is about 96-97 diesel.

Hi
Mike...
Ten quid was a bargain, then...might have been fifteen?...fluid change, sump off , clean filter and refill (I bought the fluid), and a test-drive....I think it was a fiver for a coolant change on the Jeep

Hi

I managed to drain the fluid out using a sink plunger pump brought from Lidls. Since then I have used a small bore pipe down the tube and then a larger bore and used lung power to suck it out, takes a bit of effort but cheeper than a pela pump and got the fluid out OK.

I also managed to find the filters etc which were slightly different fromt he pictures, but it wasn't too technical to clean up, very satisfying and really made the box run smoother.

Good luck, Levon.

Brilliant did you heat the fluid before you sucked it out.

Ye Gods, sounds Herculean! Think i'll push my Bongo on holiday and save on diesel.

For those interested, a Pela vacuum suction pump looks like this and costs upwards of £40......



do a google shopping search for pela pump: http://tinyurl.com/pela-pump

I think I will dispense with the luxury of one of these** and use some of the wood and metal ends I have accumulated to fashion a holder for the sump so I can lower it down on a jack as the retaining nuts/bolts are slackened off.....(I have made similar to lift my Mini on the bottom of sump - solid aluminium and man enough for the job, in this case)

**unless anyone is willing to be part of my learning curve with my own unique brand of entry level liposuction?

be aware the oil in the box is an inch or 2 over the gasket

so the trick is to try and get it leaking in one corner to start
