R-134A. It's the only commercially available refrigerant approved for use in automobile air conditioning systems.
R134a
Would have been built for R12, can be converted to R134a.
You need to convert the AC system to R-134a type freon first (retrofit kit). Then you charge it on the low pressure side.
The Freon is added through the low side ac port. Using a gauge and the proper type Freon, fill the system to the recommended pressure. Too low or too high Freon pressure will result in the system not operating properly.
They have the 4R70W transmission.
R-134
It uses R-12 unless it's been converted to R135a.
