Hi guys some help needed please I have a 2003 l322 td6 gm gearbox the problem is the 16mm fill plug is completely rounded off by previous owner and I'm struggling to get it off any ideas im thinking of some decent mole grips
 
when my hammer and chisel fail
I’m out of options.
Problem is the plug is such a weak metal and internal itd sooner mash than move. Think I put locktite on it when it went in :eek:
 
Had to use a chisel to move mine, made sure didnt over do it when put it back had to order new one from poland (well somewhere over the water) something like £16 it was also bought a 17mm single hex ring spanner to fit new one with a normal multi point ring is too loose a fit and rounds plug off . It has to be spanner job not a socket because there not enough room between prop shaft and gearbox for one.
 
Drop the front prop and give yourself more room. Then get some good molegrips and get a really good bite on the plug. So you can only just close the molegrips and it'll shift. It's a soft as shïte the plug so the molegrips can sink there teeth in nicely. If not then hammer and chisel would be next. ;)

Did BMW/GM just use random bolts from the parts bin? I did my gearbox (Td6) last weekend and the filler plug was a countersunk T50, a badly chewed one and so tight that I was gung ho in the end, convinced I would have to drop the gearbox, but without warning and with a grazed couple of knuckles it finally gave way. I was mighty relieved, good luck with the mole grips
 
Reminds me of an R380 box that had a stripped filler plug, ended up filling the box through where the shifter goes.

Bloody farce!
