Borg warner gearbox problems

Post by noel6071 » Mon Aug 19, 2019 7:42 pm

Good evening all, I am looking for some advice on my Borg Warner gearbox on the SE5a. There is a leak underneath the box I haven't checked it fully but underneath the box has been leaking for some time. The car has not been in use the last few years so perhaps its a seal at the bottom of the box i'm not sure. I checked the level with the dip stick and showing there is no oil in the box, i'm not sure is there some other technique to checking the oil level in the box and i'm afraid obviously to use it with no oil in the box.

I think you will have to put oil in to trace the leak - the level is checked with the engine running and the gears cycled through a few times - obviously not something you want to do with no oil so you have to find and fix the leak first

Thanks Peter, where is the oil topped up? How much oil do they normally take?

The bw box takes 6.4 litres of ATF, I've always topped up auto boxes at the dipstick tube with a funnel . I'm sure if that's not the right way, someone will put me straight!

The bottles come with a narrow tube end so you can top up through he dipstick tube - as Ian says

Worth checking the small bolts that hold-on the autobox sump pan. I had an MOT fail for an oil leak from my C3 box (very similar to the BW) which was just the bolts that needed nipping up.

You top up the oil through the dipstick hole (needs a small funnel and a steady hand, or the oil may come in a container with a spout. Do it slowly and carefully as there is no drain plug - if overfilled you need to suck it out again, or drop the sump. It needs to be AQ-F fluid (Ford spec M2C 33F/G)

As Peter says, check the level hot after cycling through the gears.

Correct method, wrong fluid. AQF for the BW35 and C3 with black dipsticks.

In my efforts to ensure I passed on the correct information, I crossed checked before posting, the RSSOC workshop manual and the owner's handbook both of which specify ATF. I can only surmise that this information is now out of date.

The problem, I think is one of confusing ambiguous terminology. ATF is a convenient abbreviation for "automatic transmission fluid". It's important to get the right spec - this is specified in both the handbook and the manual (the one sold by the club is a reprint of the official Reliant one) as Ford Spec M2C-33F/G, and that is the spec of AQF (or ATF type Q). So, to be sure you get the right spec from a supplier it's important to quote that more detailed spec, otherwise if you just ask for "ATF" they may assume a later more generic type, which won't be right.

Black dipstick = Ford M2C-33F oil.
