    The fluid in my tranny is brown, with a slight red tint. Does this mean my tranny is getting to hot, or do I just need to change the fluid? Its a stock 700r4 in a 84k5. Thanks.

    When's the last time you serviced your tranny? If it's brown, you'd better change it out NOW. Your ATF should be bright red...........all the time!!!!!!! Once it starts to turn dark red, it's time for a service.

    If you've recently changed your filter/fluid, chances are your tranny is running hot. Unless you're doing some hard wheeling or towing though, your fluid should last around 15 or 20,000 miles. Another way to roast your ATF is to drive around town in overdrive............but you already knew that, didn't you?

    Change it now or get it changed. 700's are very tempermental. Don't give it any reason to blow.

    I'll have to check and see when it was last serviced, but I don't think its past due. I don't drive in overdrive around town, however about a week ago it was pulling some very long grades on the freeway in drive with the peddle to the floor. I think this may be what caused it to turn brown. Thanks for the help, and I'll change it tomorrow.

    tranny fluid goes from, dark red to light almost pink, clear, brown, black. Brownish red sounds fine as long as it does not smell burnt. Trans fluid will always turn colors as it breaks down (heat). Both my blazers 87 and 89 always had a brownish red tint to them. both well over 100,000 no problems. But if not serviced in a while go ahead and do it.

    Look for a shop that has a T-Tech machine, it puts about 14qts. through the whole system (including the cooler and all the lines). Works pretty slick and makes the tranny feel a lot smoother and tighter. Definitely worth the few extra bucks for. IMO

    Why do people keep calling it a Bronco!!!!! [​IMG]

    Go to the local lube shop and have them run the machine on it.. they did mine in 15 minutes.. all new fluid... best 60 bucks to spend.. if it's brown, it's probably never been changed... NOT GOOD... Go get it changed.... SOON...

    I was going to have mine run through the T-tech but they want to charge 179 around here. So I said screw that. I got the TCI deep pan with the drain plug. I ran it with a new change, then after 200 miles I changed it again. And now I am on mine my way to the next 200 miles where I will change it again. This is flushing it like the T-tech but it takes a little longer.

    Will work for beer, parts and tools.

    Why chance fate. It is cheap insurance. Change it even if it is not time. If you think its a problem, change it. What's 20 bucks in the overall scheme.

    Does it slip at all? Get new fluid in it and watch the color of it closely. If it turns brown relativly soon then your tranny is burning up. I think tranny fluid turns brown only when it's burning up, but not sure. That's why I would put new fluid in and watch it closely. Hope this helps!
