T25 Gearbox question.

Hello to everyone.

I need some advice about identifying a gearbox/transaxle. I have read a fair bit about them on various websites and most seem to have the same info; i.e. there should be a code stamped on the box a two letter code denoting the type and a longer number starting 091/094 and so on. But this information is confusing me a little.

I recently bought a gearbox off ebay, the gearbox was an incidental purchase as I was after the diesel conversion stuff and the box came with it. On checking the box over for the codes I found three of the longer number codes, but could not find any of the letter identifiers. So I have a 091 XXXXXXX code on the petrol bellhousing, a 091 XXXXXX code on the middle section of the box, and a 094 XXXXXX code on the end.

Does anybody have any idea which code could be right? Or would I be right in thinking that the box has been assembled from a couple of boxes?

Any thoughts or advice would be appreciated, as I need to make a suitable choice of engine for my conversion. Have the diesel bellhousing, bars, sump, pump and so on for my T25.

Thanks in advance. Paul.

091 are 2litre baywindow gearboxs and are very sort after. A t25 neads to have a side shift on the nose cone were as the 091 box is not so I dont think it will fit unless it has been converted.

a 2litre T25 boxs should be cheep as chips to pick up so I would suggest you buy another and sell on the one you have-you should be able to make a few quid!

Hope that helps chap!

The gearbox code is stamped into a machined bit on the bottom of the box, the numbers you quoted are the casting numbers not the gearbox code.
