Transmission has a pipe tread el behind one of the rear wheels I don't see and overflow plug to see when the transmission is full. The insructions say to put 5 qt sae 30w oil. There is nowhere to release air trapped in the transmission so the bebbles come out the same hole you are pouring oil and you end up with more oil on the ground than in the tranmission. Tractor is 1975 SS 16 with high low 3 speed transmission. Also where does the wire from the Staring switch marked "I" connect. The scematics show it going to the coil,but it is only 16" long and has a round bolt terminal. Any help would be appreciated. BigC.

Welcome to GTtalk BigC. I haven't owned a sears yet so I don't know.

 

Being a Holiday A lot of our resident Sears experts maybe out and about today. But I am sure they can point you in the right direction.

There is a pressure release valve ( vent) on the right side of the trans-axle,  toward the rear, near where the Hi / low selector shaft comes out. they often get plugged up. I'm fairly sure that they screw out, and could be cleaned with some disc brake cleaner.

When I have trouble getting fluid in, i use a piece of aquarium air tubing shoved thru the funnel and into the fill opening  to act as a vent. just make sure that the end of the tubing   is above the level of the funnel so that it doesn't get oil in it.

As for the wire from the I terminal, yes.. it goes to the coil.

I would use a marine oil pump that fits onto quart bottles.  The hose will slip through the fitting all the way into the trans case, so the bubbles won't fight you.  Walmart has them, as well as marine supply stores & more.  I have the same problem filling some of my hydro diffs, and this pump was a super fix.

:welcometogttalk:  :wewantpics: , yes the directions are correct. It does take SAE 30 and 5 qts of it.  Don't get fancy, alota people will tell you to alter the type or amounts of fluid. Stick to the manual.  That wire does in fact go to the coil.  If you need help on any of this such as a visual, just ask, many of us can post pics of our own stuff or email them to you as referance.  I have also, along with others, posted manuals and diagrams of all sorts of things so in the manual section you may find what you need as well.  One more option is always youtube.  Believe it or not there is alota helpful info there and great visuals.  Glad to have another tractor fan with us so have fun and look around its a great forum......POST PICS.......

BigC;  Welcome to GTtalk, as you have already found there are many helpful member here.

 On filling that transmission, don't get into a hurry-it will alll go in as advised, just make sure you have drain ALL of the old stuff out.

 

Also it is suggested pictures help a WHOLE lot.

Pictures of my SS 16. Have rear of tractor and the engine and sheet metal for the front painted. I only get to work on it  an hour or two a day and work in a partially heated garage. The warm spell last week helped. Will let paint dry til Monday and start again. Only leaves the hood to paint. While looking at the manual it showed a washer under the left rear motor mount. Anyone know why.

Welcome to GTT fellow Ohioan.

Yes, filling those trannies are a royal pain in the rear. Took me about 45 mins to fill mine, I even heated the oil in a water bath on stove to make it thinner. I just sat there pouring a small stream in letting it conitnually burp. what a pain. The factory oil lasted 35 yrs so I doubt I will ever have to do it again.

Easiest tranny fill I have done.

put shifter in neutral

remove the shifter.

4 bolts a little tricky with the safety switch

plate.

Remove the regular fill plug so it vents.

Set your funnel in the shifter hole and pour away.

You need a little patience getting the shifter and bolts back in

small hands help  alot here

Don't forget to put the fill plug back in

And if all old oil is drained completely

It will take the 5 quarts

Hope this helps
