Anyone else have this problem? Engine has 200K+ miles. Trans was replaced with a used one had bout 88K and i noticed not to long ago it was leaking. Im pretty sure i know from where its leaking but i dont have a clue how to remedy this. (new lines new seals?)

 

What Year of Blazer is this you are Planning to be working on soon ? I no we are All Good Mind Readers on the Forum. Little More Info PLEASE

 

Oh I thought I had covered all the bases, guess not. lol
Its a 98 blazer. 4dr 4x4 4.3 vortec. anything else ya need to know?

 

Well, considering that there are a number of locations that transmission fluid can leak from... Cooler lines, cooler connectors either at the radiator or at the transmission, pan, front seal, rear seal, or out the breather. The cause and subsequent repair depends on the location of the leak.

 

I have it tracked down to somewhere by the connector to the radiator.

 

I had the same problem with my `94, when I replaced my radiator. I could not get the flared connection at the radiator to quit leaking. Finally I just wrapped the threads with Teflon tape and it stopped!

 

Yeah I guess I kinda answered my own question..
another question i have though is, would a 93 GMC jimmy transmission match up with my 98s? theyre both the 4.3 so i was thinkin they would
