I went to changing my transmission fluid and due to recently having Welter exhaust installed, the transmission fill plug was extremely difficult to take out. Making a long story short (not having the right wrench on hand and determined to get it off), can anyone provide me with the part # for it? I have looked at the OEM part number lists but it is difficult to determine the part. I got it off and back in but I wanted to get a new one and get the right wrench for future use. Remember this is the fill plug; not a drain plug. Thx
Looking at the parts break down from almost anywhere...
Appears to be item #8.
Part number 5138161
Part name Cap-Vent, 1/4, NPT.
Easiest way to verify woud be to call your service dealer and have them quote you a price, They think they have a sale and you get the info.
You can also check with a GM dealer for that part.
The GM part number for the fill plug is - 89060096, tighten to a torque of 27 ft/lbs
Great to have several vendors around here who are always popping in and answering questions....
