G..G..G..Granville.........!! Fetch your cloth.
The transmission hydraulic control is located on top of the transmission. The modulating valves and main relief valve are contained in the hydraulic control. Each of the five transmission clutches has a separate solenoid-controlled modulating valve.

So there are no forward and reverse solenoids ....Where on top is trans control located under seat or floor board ?

Five clutches in total - direction clutches (forward & reverse), 1st, 2nd, & 3rd speed clutches.

The control is located right on top of the transmission itself. Go to the back of the machine, remove bolts 1 and cover 2. Unbolt & move the power train filter and the primary fuel filter/water separator out of the way. Remove the cover 13, the solenoids are right behind it.
