Hot Fluid

[85 Riviera]

I have been working on my trans alot lately trying to get she shifts perfect and I finally got them doing really good but in the procees I used cheap fluid because I was losing so much droping the and twice a week and stuff. Now with cheap fluid I notice that the trans will shift softer after about 30 minutes of driving with the A/C on in my hot city of Tampa. I have a cooler but I think it might be the fluid more than the actual temp, Where can I get that tractor fluid and whats the exact name, is that tractor as in bob cat or semi. If I cant find that tractor fluid what do you think the next best fluid is for high temps? Thanks for any advise

Here is one of many, there are differ brands, try searching "tractor fluid" on here. If you are draining your fresh oil into a clean container, there is not a problem with reuseing it, just keep it clean.
