Been doing research on why fluid to run on my TH 400 and have had a lot of mixed reviews. What are u guys running and why ??? Thanks
We run Swepco hydraulic transmission fluid in the trophy truck, and I run it in my boat as well. It handles heat better than anything else. All last week at the Norra off-road race we were continually seeing 280 temps on the trans, and the oil is still bright red. Sent from my iPad using Tapatalk
Just food for thought but the torque converter is where most of the heat is produced in an automatic transmission. Since there are no torque converters in our boats, they do not see the same temps as a wheeled vehicle. Coolers are nice but essentially overkill in a boat (I run one anyway though). I run Valvoline Max Life Full Synthetic in my TH400. It always comes back out red.
Keep em coming lol , pulling the motor out for oil change and resealing my prop guard and going to change out the filter on the trans . All of it was rebuilt last year and has about 15hrs run time . Want to have a good summer lol . Just love how easy and fast it is to pull everything out on my boat .
