New tranny is in and works great I guess this shows 2004 is a compatible application with the other years the trailblazer was made. The only difference was the upgraded pns switch plug had 1 large plug instead of the older 2 small plug connections. So unless you have a 2004 style pns switch...

********* Transmission swap Update : Despite a little scare after start up and test drive , the new transmission is working great and the pns switch swap was a success! The transmission would not shift out of first gear at first so after a mild panic and brainstorm to try to think of a...

That is exactly what I ran into when I tried to remove the harness from that switch , It would not come free of the switch untill I cracked the casing on the switch side. I have already changed the switch AND had already broken the switch before reading your post so I was relieved to read it...

THanks marine yes they both fit over the shaft and mounting holes line up fine . Im gonna give it a shot I just dont want to get it in and have to pull the tran back out, My gut tells me it should work but all references I find only show up to 2003 compatible with previous years and 2004...

I6 I stand corrected and yes everything about the switches look the same except for the plug connections

I am swapping 4L60E trannys from a 2002 trailblazer v6 to my 2004 trailblazer. The plugs on the switches are different as u can see in the pics. Can I use the old safety switch from 04 on the 02 transmission or not?

ok guys im ready to stick this transmission in so i decided to look them over a little closer for descrepencies and right away the park-nuetral-safety switch has 2 plugs instead of the 1 larger plug harness the old one had. Im hoping I can just swap the switches and reuse my one plug but i want...

{Yeah that would be great since Money is an issue for me right mow I would appreciate it and would be sure to return them as I got them. I cant see throwing the money away I think a rebuild is def, in the near future. Ill keep you posted on the swap and when I get it done if you could do that...

Thanks marine that is exactly as mine looked as well.

Well I got the $250 transmission , it has good red fluid in it, as it should. I realize the seller could have poured fresh fluid in it before I got there but the truck was wrecked in the front end and slightly twisted the frame so had to be salvaged. It was obviously working at the time it was...

Thats what I suspected. I have found a really good deal on a used replacement from a tb that was wrecked in the front end engine and tranny doesnt look as if it would have sustained damage and assuming the tranny was working when the wreck occured then I cant pass it up for only $250.00, Bad...

so basically I just mixed 5 quarts of new fluid with 6 quarts of old?

iI only dropped the pan and replaced fluid I never flushed the system. Somewhere on the forum I had read where someone posted to disconnect the trans cooler line on passenger side of radiator and turn the truck on to pump as much fluid out as possible and reduce the mess of dropping the pan. I...

yes the fluid is just as dirty as before , no red color in it at all . in fact it looks like oil only not nearly as thick as oil or even tranny fluid should be. Illogic ...thanks for your input and I have also read about the dipstick but didnt consider the coolant lines. Hatchet ...Thanks...

Hi Im new here but hoping to get some useful information that will shine light on this situation without swapping or rebuilding the transmission. My wife has a 2004 trailblazer , about 6 months ago I replaced tran fluids and filter. At that time I noticed the fluid was very dark and appeared...
