How hard is it to replace the brake fluid the tranny fluid and the differential fluid? I tried looking for threads about this but the ones I found weren't very helpful. Please give info on how to. Pics would be great on where the bolts are. Thanks!

 

Automatic or manual?
Manual has a fill and drain plug(s). Uses the 3/8" drive ratchet head to remove the plugs.

Automatic, I have no opinion. Many shops use a flush machine. Some DIY'ers just drop the pan, replace the filter and refill (leaving a lot of old fluid still in the torque converter).

Front differential gets sucked out.
Rear, take off the cover to drain. Use black RTV to seal the cover.

Transfer case has a drain plug under that damper.

Brake fluid, I'd suggest a vaccuum bleeder. Suck all the old out of the MC, fill with new (keep topping it off) and suck from each wheel's bleeder till new fluid appears.


It would be wise to buy a SERVICE MANUAL for your truck. Even the crappy Haynes and (slightly better) Chilton manual would have answered all these questions in an easy 1/2 of reading and looking at pictures. You'll be glad you bought it.

 

do you mean that you need bleed the brake lines to get air out of the system, or do you need to replace the fluid because it is bad?....either way, bleeding the brake lines requires two people. One person to pump the brake pedal, and the other person at each wheel to open and close the brake line bleed nut. I don't have any pics, but that should be pretty easy.

As for the tranny, do you an auto or manual. They are very different and require different fluid.

And for the diff, just remove the cover...10 or 12 bolts. Let the fluid drain out. Replace the cover with a new gasket and fill it with the proper fluid, usually a very heavy weight gear oil. There is a fill plug on the diff cover and just fill the diff until it starts to pour out a little bit. Do not overfill anything!!

 

It actually requires only one person to bleed the breaks. They have this part that you put on the end of the bleeder screw and it creates a vaccume pulling the air out.

 

I got an automatic transmission. I want to flush the brake fluid and replace it with new.

 

never done brakes. i dead the rear end and it was easy. id say a 2. (some of the bolts were pretty stubborn lol)
the tranny is a little harder. a few of the bolts to drop the pan were hard to get too and just making sure everything lines up so ill say a 4.
but neither are really that hard. get a chiltons/haynes and go do it!

 

Never done an auto tranny but everything else is super easy.

 

Oh yeah, I have heard of those, but I have never used them. Good point!

Me ether. I do it the old fashion way. My friend has one and he uses it and his brakes still work. lol
