CTA Tools 7425 ATF Filler Adapter for Infiniti 7 Speed

Hi all,

I've been following this thread for a few years now. I finally worked up the courage to perform the ATF change and was surprised at how straight forward it was. Mind you, I didn't drop the pan after reading what happened to Dan G37. Also, my car only has about 70,000 kms (44,000 miles) on it so I don't think it's a big deal (the fluid that I extracted wasn't THAT bad!).

I don't know why everyone is still using makeshift adapters for the filler. I bought the proper tool on Amazon for about $20 and it worked like a charm:

Hope this helps!

Good link^^, that makeshift adapter I used was simple enough TBH, and very fast since you don't have any threading to do but a few different ways to tackle this DIY

Also the infrared temp guns work great for this project and are now very affordable.
