Quick transmission/Guibo question...

[AutoXinE30]

Was going to put the I motor from my 89 325I into the the motorless 88 SETA I have in the garage... But the guibo from the 89 was tore up and I was going to use the guibo from the 88 till I realized the bolt holes on the 88 SETA G260 are larger then the ones on the 89 G260...

Can I swap the 88 G260 output shaft onto the 89g260 and use the 88 guibo? Or do I need to put the whole 88 G260 onto the I motor?

I have already chucked the 89 guibo since it was torn up... Are the bolt holes in the 88 driveshaft also larger then the 89 driveshaft?



edit: Apparently 5/86 + 325e's and M3's came with the large hole output shaft, and apprently ETA and M3 driveshafts are the same length?

So I can infact just swap this output shaft in place of the smaller one and be GTG? Can anyone confirm that?

You can swap the transmission output flanges, but if you do use a new output seal.

The nut that holds the flange on has thread locker. Use a torch to heat the nut up to 350-400F before attempting to remove the nut.

Yes, they swap. Make sure to take the safety clip off. I've never had to use a torch, just an impact and 30mm thin walled socket.

Swapped one this week to replace a worn transmission in a client's car.

Thanks for the replys fellas.

I ended up just pulling the small hole trans and reinstalling the big hole on the motor before it went it rather then swapping the flange... It was quicker the searching for a rear trans seal. I would have likely had a hell of a time with the nut too as, all I have at home is an electric impact.

At least I know I can save this G260 for the future and just swap flanges.
