if you open it up you will see there are a lot of small passageways inside. Before you open it, you need to get a couple worm clamps together from home depot to line it up perfectly when you put it back together or you will never get it seated back in the trans.

Did you see black fluid when you dropped the pan for the shift kit?

yeah. I was told by a trans builder that alot of trans that come from junkyards or wrecked trucks have black fluid. He said just to change the fluid and filter and I should be good but I'm still a bit skeptical

A lot of older transmission's fluid will be dark in color. That just means its old and has some wearage to it. And its a possibility its on its way out. If you have the ability to rebuild, it wouldn't be a bad idea. Because its just a matter of time before it will go out.

When fluid is burnt like that, its definetely overheated and when this occurs so has damage to the internals. I would rebuild it without a doubt. Do you really wanna try a new converter in a transmission that is guaranteed to fail at some point?

Oil will start to discolor within 1000 miles of use, im sure that tranny fluid is no different, just do like the guy said and clean it best you can and dump new fluids in it, If it was me I would change the fluids a couple times to get all the old **** out before you go in and put your new good fluid... but thats just me-

My truck has 32000 miles and the fluid looks and smells like it just came out of the bottle, tranmission fluid isn't like oil. If it looks or smells burnt, that means it is and so are the internals like the clutches. Thats not good on a 4l60, they can not hold up to heat.
