The antifreeze is not coming from your transaxle actually it is usually from your intake ,running down the trans case. This is a very common problem that 3.1,3.4 lt have is leaks at the intake.You have to replace your intake seals. But check under your throttle body ass. to make sure its the intake and not the heater hose connection that runs underthere.
Dexcool is recommended.
Pentosin Type G12.

A small radiator leak can cause antifreeze to leak on your 1998 Chevy Lumina when there are not any spots on the ground. A pinhole in a hose can also cause this.
add to coolant recovery tank!!!
A 50/50 mix of water and antifreeze
There is not a camshaft sensor on the '93 3.1 Lumina, just a crank sensor on the back side of the engine between the block and the barrel of the transaxle. Easy enough to get to from underneath the car.
I had this problem with my 1998 Lumina . sometimes it would start but not very often. Sprayed WD40 in the key hole and Blew it out with compressed air. Cleaned the chip on the key. Starts every time now.
My 1990 Lumina 3.1 had the same problem and it was caused by the crank sensor.
If you have a 3.1 it is on top of the engine but if you have a 3.4 you have to take the right side tire off then remove the transaxle then it will come out through the hole where the transaxle was 3hrs repair time. I have one of these. also you do not have to drop the engine as some repair manuals tell you.
A 50/50 diluted mixture of DEX-COOL. I would recommend Havoline. You can get that at any parts store.
because it is old and has begun to leak
