Default 8N Transmission Flush?

I'm going to replace the oil in my trans this weekend because it's a bit milky so I'm concerned about contamination. Is there anything I should use to flush it over I take out the old fluid or will the new fluid be sufficient?

I had been intending to put the procedures (that I use for this, anyway) into a sticky...

You prompted me to do so...

Got it, thanks. I figured there was some way to do it. This old 8N was used pretty hard but doesn't appear as though it was taken very good care of. I wish I had gotten some of the before pictures (I've started going through it and clean/paint stuff as I put it back together) so everyone could appreciate what a basket case it was

The 8n, same as the 9n/2n, has a one sump system, trans,hyd,rear. So if it's milky in the tran it's also milky in the hdy and rear. 3 drain plugs one fill plug. Don't over fill it.

Roger that. I went to pick up the new oil and they only had one bottle so I'll have to wait until they get a truck in this week to get the other 2. I do have a question though. I've seen several references to "inspection ports". I looked at the tractor last weekend and don't see any. Can someone put up a graphic that points out what is being referred to?

Sorry I couldn't find a picture but it's the plates on the side. The "drivers side " plate is where the PTO engagement lever is and the "pass side" is the plate where the dip stick for the hydro, gear and transmission is. Just take out the bottom bolt on either side to get the proper full level. Then mark your dip stick where the actual full level is.

At TSC the 5 gallon pail should be more economic in price then the 2 gallon jugs.

I did what Steve suggested this weekend on cleaning, been planning it a while.

One tip on buying your 80-90 wt. oil, you can get it cheaper at a parts store usually than TSC. Unfortuantely I found it out to late. I paid about $58 for a five gallon pail at TSC about 4 weeks ago. When I stopped at Carquest I asked them if they had 5 gallon pails and what the cost was, they had it and it was $38.

Thanks for the tip hossfly (I like that handle, we have horses so we see hossflies quite a bit) I haven't broken the seal on the oil I bought yet so I can always take it back
