Have decided to make a dipstick. Does anyone know, or can measure, the distance from the top of the transmission fill hole to the top of the oil? Thanks in advance.
I found another thread that showed the location of the oil check plug, second photo. I opened it and saw that water had gotten into the transmission and the oil was contaminated. After draining the contaminated oil I refilled it, per the owners manual, with 3.25 gallons of 80-90 wt gear oil. I then made my own dipstick from a dowel. My guess is that there was some contaminated oil left in the sump so will keep an eye on it.
