Changed the ATF in my 84 5ks today (filter was clean, BTW) and was going to change the final drive lube also. HOWEVER! neither the Bentley nor the Haynes show the location of the drain plug. I've found the (I assume) fill plug, behind the left driveshaft. Is there a drain? BTW, Amsoil ATF works great, even @ CDN$13.50+tx! Steve Bigelow Ottawa
