How much freon does a 87 Trans Am Hold??
I'm converting to r-134a and don't know how much to put in. They say 85% of what the system holds of r-12 but I don't know whow much that is. Does any know? My car is here at the shop now and that's all I got left to do. Thanks, Jason

Holy ****, mine holds 2.25 of R12. The most I've ever seen a third-gen hold was around 2.75. Maybe you have a high-capacity system. It should be under the hood somewhere.

Car: 1989 Pontiac GTA Hardtop.
Engine: ZZ4 - 350
Transmission: Garbage
The manual for my 1989 says that the system takes 2.25 pounds of R-12. I would think this should be pretty close to the same as an 87.

Your system holds 2.25 lbs of R-12. When I do thirdgen conversions, I put in 2lbs even. The general rule of thumb is 80%, but it is used as a STARTING POINT, you can add more to acheive the desired pressures, wich is about 2lbs. Its tried and tested, go with it.
