Good afternoon all,

My E82 N55 135i has a gearbox fault.
It jumps out of 1st gear when pulling away with a bang.

Apparently it's a common fault but company's cat buy replacement parts for them.
That said I thought I would get a S/H gearbox.

The codes on mine are GS6-45BZ THD4
The S/H gearbox codes GS6-45BZ THAJ this comes out of an F20 Lci M135i which has done 29k

The guy says it's the same box but the price is ÂŁ1250 delivered so obviously I'm wary of spending that kind of cash to find it won't fit !

Can anyone shed some light on these codes and if this replacement gearbox will be ok ?

It might be worth having a poke around on realOEM
Use your car's VIN to ensure you have the correct vehicle. If you check out the gearbox section it might show if there were newer parts which are compatible or not.
