A bad day for transmissions........

[Titsy]

Anyone local got a garage I could pull the 'maro (or front end at least) into to fit the baffle? The weather for the weekend don't look to good, and I don't fancy rolling around on the floor for hours on end if it turns out to be a PITA to fit....

Well, if I had a set of ramps . . . . .

[Titsy]

I doubt the 'maro would go in on Caddy ramps, ground clerance is a little lower...

I get enough stick for using the garage when i do, don't think inviting my mates round to work on their cars in there too would go down too well...

The ramps are designed to suit a ground clearance of 6.5" . . . . FYI . . .

24miles across country isn't really local when you have a car that overheats...

Well it that's or get wet outside.

Fitted it this morning and went for a test drive..... Doesn't seem to have helped at all....

Plus, to compound my problems the oil pressure seems to have dropped through the floor....

Bummer Mate, is it worth giving the fluid lines and box a good flush through ?

It ain't much fun having a red dexron bath but the last thing you want is the box going AWOL again

Yup.... Any suggestions on how to purge and flush the box lines and cooler?

Any suggestions on how to purge and flush the box lines and cooler?

I'm thinking disconnect the cooler oil lines as close to the box as possible, then connect up the feed line to an airline ( compressor ) and blow all the oil out into a container. When I change the gearbox oil I use one of those large plastic under bed storage boxes on wheels ( cost £8 but you can borrow mine it you want )

Blow all the oil out into the "clean container" until you have a good flow of air back through the lines.
Now if you have a contamination problem it should be visible in the flushed oil, if the oil is a nice ruby red colour and clean that crosses the cooler and oil off the problem list.
It also saves you dropping the gearbox sump coz it's messy and costs a few quid in oil.

If there is a contamination problem, you'll have to drop the sump, change the oil and filter, run it again for a few miles and repeat the process.
The only way to check the filter for contamination is to break it apart once it's out
If you do buy the filter set make sure that you order the cork pan gasket ( the standard filter & gasket GM part No. 24200796 - £47.54 is paper and is a b!tch to seal )
The cork sump gasket is only £3.77 from USless Automotive

Another key point , the sump bolts should only be tighted to 8lb ft which is bearly more than finger tight
I had a slight oil leak last month and just went round and nipped up the bolts just 2 flats more - sorted !
I've done the oil change five times and it's messy, the first time I left the gearbox draining for two days and it was still dripping !

If you need a hand give me a shout

Found some of my pictures :

Plastic bed box :



Standard GM filter set with paper gasket



US Auto Mr Gasket cork sump gasket




Make sure you seal both sides of the gasket with good quality high temperature silcone gasket sealer before fitting. I find that hermite gold works best. Remember that the oil level is always above the gasket joint !



This is what the gear box looks like with the sump off :



Did I mention it's messy ?



The M8 sump bolts which tighten through just 10mm thickness of aluminium:

So any ideas on the cause of low oil pressure? when was the last oil chnage? was it flushed?

when was the last oil chnage? was it flushed?

Not a clue, was planning on an oil and filter change for exactly the reasion that I don't know when it was last done...

Chuck some flush through at the same time....

The other thing it could be is a failed presure sender
