Transmission lost fluid on the highway

I have a 1993 blazer with a V6 vortec engine and a 4L60E tranny, st first the tranny had a hard time down shifting gone up hill> I would leave it in drive after a few seconds it would shift. same when i used overdrive. I add a tranny additive and a little more fluid. it seamed to run okey for about a hundred miles then I lost power and pulled over and the fluid was everywhere. put a quaet in and drove it home and drained the fluid that was left the fluid was a redish brown with a tint of black. coud it be just the filter has not been changed in a long rime I just bought it. or maybe a sensor. please help.

What has probably happened is you have busted a tranny cooler line or transmission seal.
The reason your fluid is brownish black is due to running it with all the fluid coming out
and thus taking the life force out of the tranny, the black tint you are seeing is flakes
of your clutch packs inside the transmission that have worn prematuraly due to lack
of lubrication.Long story short, when you fix the leak, more than likely your tranny
will slip and warrant a rebuild or replacement. sorry to be the bearer of bad news but i
hope this helps.

When I put my pedal to the floor, it just revs it seems like that harder I push the peddle the slower it goes. It feels like it's not getting gas when I press the pedal all the way down.. also. Fuel pump...

Catalytic converter could possibly be clogged. Are you getting any sulfer smell? especially when going up hills. Also if this is a vortec motor ( says VORTEC across the top of engine) they were famous for have the injector module leak in the intake.

I own a 1998 Chevy Blazer 4wd that is on its 3rd transmission and I'm having the same issue where when shifting from 2nd to 3rd gear it's slipping badly my rpm's rev up to 3500 and I have to take my foot...

this is a known issue with the gm 4L60E transmission. the valve body in transmission causes this. if it is wore, then less fluid is sent to shift selonoids. thus causing torque convertor not to lock up, and this causes slipping. if it slips 2 consecutive trips then the transmission detects this and should turn on check engine light. ( p1870 ). you can see if the tcc solinoid is bad. but if not its usually the valve body in tranny.

1999 Blazer -4x4 4.3 liter 140,000 miles- lost prior problems or symtoms...happened pretty much at once, Fluid ok...linkage appears to be ok....time for new tranny?

That year of blazer would have the electronic transmission in it, a 4L60E I believe? A pretty common problem I have seen with people who have the same kind of vehicle is the control module for the transmission and not so much the transmission itself, especially in 4x4's. Often times this problem occurs after going out wheeling, and it's often as simple as reconnecting the plug on the tranny, or pulling it off and cleaning off the contacts, or if that doesn't work then head to the junkyard and pull the module off of one from there (and hope that it didn't have the same problem)

4l60e tranny swap

No the 4l60e is a electronic transmission you need to find a 700r4 transmission which are very common. Check with your local junk yards and are pretty easy to install. About a full days worth of work for a person with general know how of vehicles.

Custom buggy wrapped on Astro AWD

All depends on the 4.3 your going to install. The transmission are the same, that both use the 4L60E. E being that the transmission is controlled by a ECM with the engine. If your running a Aspirated 4.3 and not fuel injected, your going to have to run a 4L60 transmission. 
As for the AWD the new AWD system on the Astro works off the ABS system as it runs on 2WD till the PCM detects the lost of traction then the transfer case is activated by the ECM.
The earlier Astro and Safari AWD 1991 to 1994 had a true AWD and stayed active, but was not that great off road since it had a 40/60 split ratio front to back transfer.
Good luck and hope this helps.

Does it still have park? If not, check the differential. It is very unusual for a 4L60E to just completely quit - especially if it is clean.
