I have a 1994 Chevy S-10 Blazer Full Size, 4.3 Liter V6, with a 4L60 E Transmission 4X4, I don't know where the Transmission could be leaking from? I replaced the Seal's in the front the torque converter, oil pan seal, the seal on the input shaft, seal in between the transmission and transfer case, and the transfer case output shaft seal, I replaced all the vacuum hoses, on the Transmission and Transfer Case, vacuum switch, and vacuum actuator. It seams to be leaking somewhere along the Bell Housing? Drive 40 miles and there will be nothing at all on the dipstick, it shifts fine, 4X4 works great, Please help me ASAP thanks Sean

You could try adding transmission leak dye and use a dye light to trace the leak back to its source. It Could even be the transmission case leaking its hard to say your my eyes on this one.

Yes auto parts stores have it and you would use a uv light auto parts stores will have the light to go with the dye. You could have ahairline crack or something else.
