hi, just joined here. been on all the other grand prix forums since about 2002. this is just my first transmission question and this forum seems like it has the best info.
short story: lost 4th, did a trans swap to a low mile ZZP rebuilt tranny, shifts great, but leaking from reverse servo area.
pulled the reverse servo assembly out of my old trans and pulled the one out of the new trans to compare...
new trans looks like it has the newer designed (larger) o-ring. also has a heavy duty large spring.
but old trans didn't leak from that area.
would it make sense to put the old reverse servo assembly into the newer trans?? or maybe put the old one in, but use the newer style o-ring. if the heavy duty large spring is 1/2 a millimeter shorter, would that really make any difference since it takes less force to compress?
additionally, how do you force it back down to reinstall the snap-ring?? seems like it takes some force.
thoughts?
thanks,
james
