MG MGB Technical - 1973 MG Roadster transmission fluid

Please tell me where I can check and fill the transmission fluid on my car. It is a standard transmission.

Thank you,
Juliet Pierson

Juliet,
Behind the centre console, probably under a flap of carpet, near the driver's side, you should find a large rubber bung. Remove it and grope about, you should find a metal loop (sometimes with a cable tie in it) which is the end of a gearbox dipstick, pushed into another rubber bung in the gearbox itself.
All depending on whether your box has been changed at some time for a later one, which will involve groping round underneath to find the filler/level plug, on the side of the box. R/H side...I think.
Allan Reeling

Yes right-hand side for the later (RB) side fill/level plug gearboxes.

If there is no cable tie or similar they can be a real beggar to get out (two O-rings on the dip-stick itself in my case rather than a rubber bung in the gearbox casing), so fit one if needed before putting it back. When putting it back you will have to feel around with the tip of the dip-stick for the hole, mine is slightly offset from the hole in the gearbox tunnel.

Yep Paul, I couldn't remember the O ring, dip stick fitting.
Allan Reeling

depends though if it's a real late B it could have a screw in level bung
Or maybe it's auto--??

Willie, Juliet said it is a 1973 car with standard transmission. The gearbox dipstick was deleted at the start of rubber bumper production, according to Clausager.

Allan also mentioned it could have been changed to an RB side-fill box. Can't take anything for granted after 40-odd years.
