Hey guys just curious but at about how many miles would ya'll change tranny, coolant,and rear end fluids? Never had a new vehicle nor kept one long enough to do these lol.

 

newer vehicles (depending how hard they are ran) can be changed at 100k.

 

My recommendations:

Transmission fluid & filter at 50K intervals, coolant at 100K intervals, and differentials & t-case at 60K intervals. Some aftermarket diffs require 30K intervals.

 

The rear diff should be changed much sooner if you have a locking G80. You will be surprised how dirty the oil is with clutch material. I would do it at 5000 miles.
Even though the trans fluid calls for a high mileage interval it still breaks down and is dirty. If you plan to keep your truck the trans will last longer with regular services.

 

50k for sure on the trans, and NEVER change the fluid trying to remedy a weird trans problem....you are almost instantly dooming it by doing so. Thats why you want more often trans service on apps running hard.

 

As soon as you get out of the mud hole/deep water!

 

Just follow the owners manual. There is some actual consideration that goes into the intervals, not just opinions.

 

Thanks guys I sure appreciate it!

 

I did my tranny at 50 and the fluid still looked new, the magnet in the pan was a different story. I am at 60 now and am about to do my rearend.
