what'smy gearbox?
 

Hi guys, I am trying to get some new oil seals for my hot rod's gearbox, but I don't know the origin of the box, I have been told it's from a Sierra. No-one will supply me with the seals unless I quote the type! Maybe one of you clever guys could identify it for me from the numbers on it. They are as follows:

Large 'B' on side
83 ET7AO39 BA
71 WG-7006
83ET-7006 28+
G24525 LK82
Gearlever held in with 3 bolts

Thanks for any help.:?

is it 4x4 2wd? cast iron or alloy? where's reverse gear located? bottom right or top left?

99% it is std type 9, 4 cylinder version, v6 are different.

Hi, It is a 4 speed iron gearbox with an alloy tail extension. It has an RS2000 alloy bell housing fitted to it.( I know that much) Reverse is press down left and forward, thanks guys.

It sound slike a standard 4 speed Sierra box. I would be speaking to either Central Axle Services in Brum or Royce Power and Transmissions to get the best prices on the parts.

Thanks a lot, will try them tomorrow.

Went to central axle services, they told me it's a sierra 4 speed. They got the seals, and fitted them for me, collected it next morning. What a fantastic service, great price as well! will not hesitate to use them any time again in the future.
