Okay, so the 5spd D/Rs have a drain plug, right?

 

I'm gonna do an oil change on the transmission of my wagon since I found a brand new looking bottle of valvoline 80w-90 oil in my dad's garage as I was helping him clean out. I have no idea how old the tranny oil in the wagon is, and if its the original oil with 180k on it, may as well change it.

 

So, where's that darn drain plug?

Hi This is Jerry, if you look under the tranny where the stub axles are well in the center of the tranny there is a drain plug. Use a 13/16 six point socket you will have to tap it on the drain plug tight fit. The tranny holds about 1 galon of gear oil. Thanks Jerry
