Auto box service
 

Does anyone have any tips on servicing the auto boxes.

Oil change is basically the only service you can do on these autoboxes.

Should be done on a regular basis and with the correct ATF and procedure.

That's what I'm wanting to do. I've serviced my 100s auto box before. I'm after any tips on doing 75 auto boxes. such as how much oil the take, were to put the oil in ect.

They’re pretty straightforward, lots of info on here.
Basically you either drop the fluid and refill, run, repeat, check level and that changes the vast majority. The other method is to drop old and refil, remove a cooler pipe and run the car with the cooler hose in a container until the fluid runs clear, then Turn off immediately, two people needed ideally. Then refil, run, refil if necessary.
It is recommended they are at 40 degrees when refilling, but provided the box is warm to the touch it’ll be near enough.

I have changed mine and it is straightforward, there was a good how to on here somewhere but I can't find it, I used it to do mine.

Someone will be along who knows what and where and how much.

Thank you, Since you saw my cowley its now got a nice stainless back box on so isn't the quietest of things anymore. so I like the idea of drain refill take for a drive then drain and refill.

I made this alternative procedure for some 8 years back: https://www.the75andztclub.co.uk/for...d.php?t=124816

Reminds me that its probably on time to replace my fluid soon.....

Ah yes, that's the one I followed. Thanks :D

Very good, I hope those top struts got sorted before the back box though!! :D
