I'm pulling my trans to put in a new clutch / rear main seal and all thats left for me to do is unbolt the tranny itself from the bellhousing and pull it out. In my Haynes manual it says I should use guide pins in the top holes once I take the bolts out and then unbolt the bottom. Is this really necessary?

 

Hmm, pulled the trans in my Z twice now and probably pulled other manuals a dozen or so times and never used any myself. Since I've never had a problem I'd be inclined to say no.

 

Done this job around 8 times now, never used any kind of alignment pins or anything,

I guess they want u to use them so that the trans isnt hanging on the input shaft while u put the 4 bolts in.

 

Thanks!

 

Actually, I believe they say to use guide pins to ease the installation of the transmission when putting it back in. Its easier to align when its at the right angle. Either way, I never did it myself and ended up alright putting it back in.

 

never had a problem. I just lay there on the floor slide the trans on my chest and just lift it in. rev. for removing. never had a problem.
