I stopped at the GM dealer today and bought 3 qt.s of the Synchromesh but part number is different than the # listed in some of the treads i was wondering if anyone can confirm this for me.
What i bought is part# 12377916. on the back of the bottle is says that it is for 1500 trannies.

i haven't found any info on this other item # the desrcription on the bottle is "Synchromesh Transmission Fluid-Friction Modified"
1 #12377916
Gr. 8.800.

Any way it looks like i got the wrong schstuf. And just my luck everything is close for the longweekend.
Thanks for the info.

Well, caught you before the seal was broken, I hope. It's only a 20-minute job, you can get it after work.
