I was driving my 2000 Chevy Blazer last night, and I started to smell a burned scent. Right after I began smelling that, the car down shifted (I was on I75, going about 75mph at the time) and wouldn't excelerate anymore. It then proceeded to smoke from the engine, and trans fluid spilt everywhere. From doing my own research and such, there are no visible leaks in any tubes, and the fluid that splattered on the vehicle starts about 1/4 the way back from the front end. I am in the process of changing the seals on the trans fluid pan, but if that does not solve the problem, what would be the next logical step? I am thinking the Vacuum Moderator Diaphragm, but I can't find any diagrams about location, and also how to change it out.

hi my name is XXXXX XXXXX i can help you. The problem you are experiencing is a blown transmission cooler line. this is a pretty common problem. the best way to be sure is to fill the transmission fluid and start the vehicle. see where the fluid is coming from. this will be your leak.
None of the lines were wet though. And all of the oil started at the back of the fluid pan...
ok the best way to track it down is to start it and see where the fluid is coming from. This was obvioiuisly a very large leak to actually stop shifting like that. try that and let me know what you find
Ya, we just got the new seal on the trans oil pan, and are putting in new oil as we speak. So we should be able to start it up soon and see what happens.... after researching it though, the only other explanation I can come up with (if the seal wasnt the problem) is the vacuum moderator diaphragm. Only problem is, I can not find a diagram of how to find it and change it anywhere online. Would this be an actual possibility, if the test doesn't go right?
this year blazer has an electronic transmission and does not have a vacuum modulator. everything is controlled by the electronic control module
Oh? Well, thats where I was getting confused on my research. Some sites were saying a 2000 does, and others not. So if it's not the seal, we just have to start it and see where its leaking from? And if it does leak/smoke/smell like burning still, is there a way to re-contact you tonight, since you now know the problem....
yeah will be up for a while. good luck
Ok. Thank you. Just started it up, and so far no leaks, no burning smell. :) Taking it for a drive and going from there. If I need to re-contact you, I will be in the next 30mins ish or less. Thank you.
