I wanna say i appreciate any help from anyone in advanced I'm new to the blazer and this forum. My name is Jeff I'm from Alabama. I've recently purchased a 92 s10 blazer 4wd fuel injected for $400. I'm 30 years old and my girlfriend is expecting and she needs a car to go to here and there, nothing any farther than 10-15 mins away from where we live. We are poor at the moment both of us are in the process of starting all over again from nothing so I figured I could find something that needed work and was cheap. I found this blazer on Facebook the guy said it needed the gas tank, rear quarter glass, and idler pulley re assembled but all the parts were inside the car supposedly. I currently work as a maintenance man at a poultry plant and I've always worked on my own cars. I'm not ASE certified or nothing but I figured what the hell. I had to buy a fuel pump and a tensioner pulley bought a refurbished battery and Christmas day a few weeks ago I fired her off. Started on the first pull let her run for about ten mins. Right before we jumped in to take her for a maiden voyage I noticed a puddle of ATF. I laid up under it after pouring more and more ATF in it and it's coming from whatever the component is that is between the trans fluid pan and the oil pan. I will come right out and admit i know jack about automatic transmissions. So if anyone can help I really to appreciate it.

 

Sounds like the front seal. Unfortunately, the transmission will have to come out to fix it. Not an easy job.

 

so I've no doubt you know more about it than me so I'm not questioning your judgment im just trying to learn all I can. Oddly even with the internet at my disposal, information on this specific problem as well as 1st gen blazers as a whole, seems to elude me. What makes you diagnose it as a front seal? Also what is that part in between the trans pan and oil pan? It seems to have 2 weep holes in it or breathing holes idk and I belive the previous owner tried to caulk these holes up as if that could solve the problem lol

Thanks again for any and all responses

 

That part in between is a cover over your torque converter. You can take it off and look inside. There should be no liquid in there at all.

Two things can leak in there:
1) The rear main seal of the engine.
2) The front seal of the transmission.

Since you said you're losing transmission fluid, that points to #2. The seal in question is where the torque converter goes into the transmission pump on the front of the transmission. The torque conveter must be removed to replace it, and that requires removal of the transmission. As I mentioned before, that job is no fun.

I'm really not a "transmission guy", so my knowledge of automatic transmissions is limited. Hopefully Transman will come along and maybe give you some better info.

Additives designed to stop leaks MAY work on very minor leaks, but it sounds like it would just be a waste of money on yours.

 

I just had mine fixed. Cost me $540 at a shop since I’m not capable of doing that repair, nor did I have the time. I pinched the front seal when installing the torque converter during my V8 swap. Was leaking ATF down onto the exhaust pipe and created a smoke screen behind me when I drove.

I chose to fix mine since I new my transmission was not in need of a rebuild. If you are unsure of the condition of the transmission (ie it has a lot of miles and/or you have no idea if it’s the original), then you might want to look at getting a used transmission from a junkyard.

 

I agree that may be the best bet but at the moment I've got plenty of time and very little expendable income. Also sourcing a junk yard transmission or anything from a junkyard without someone telling me I have to buy the whole car is proving difficult. There is a "pull-apart" about an hour away, but I feel like if I'm gonna go there and remove a transmission(provided they have one) I need to remove the current one or roughly know how to. My father and I removed the 5 speed trans from a 79 Camaro but other than that he hated messing with transmissions so I never really got any experience in that department. That trans seemed smaller and that was 15ish years ago. I could probably save up $500 to $600 in a few months that might be what I do. I honestly do believe tho!!, with minor guidance from someone who has been there done that I could, maybe over the course a long time, get the job done. BTW those V8 swaps sound cool as hell i would love to see some pictures.

 

Thank you sir I shall keep my eyes open for the one they call "transmission guy"
