I'm about to hit 100k on my truck and was wanting to change all the fluids I can. I'm planing on doing the oil, front and rear diffs, tranny, and radiator?

I've been doing alot of research on the differential fluid change and think I can handle that alright. I've got a small leak from the front seal on my rear end, so I might end up changing that too.

My main question with all this is the tranny. To change and flush, or not to change and flush. I know I have never done it and probably wasn't done before I got the truck.

Would a tranny fluid change and flush be a good idea at 100k if it has never been done before? I don't want to get it changed and then start having tranny problems.

Any other input/things to watch out for on these fluid changes or any other I didn't mention would be helpful. Thanks.

 

wow... those items should have been changed twice already before the 100K mark.
so, hows your spark plugs???

I would change your coolant as well.

 

Plugs have been done once before. I'll be doing them as well. I got a set of autolite plugs and wires. I also plan on flushing out the radiator and replacing the coolant on top of the other things listed. I know all of this is well overdue, so what better time to do it then now.

I will be posting any questions or problems that I have along the way. So I can y'alls expert advice.

Anyone have advice about flushing/changing fluid in a tranny long overdue for service? Or any other advice for that matter?

Thanks.
