Good quality kit.
Kit looks nice. Build several using this kit now.My dislikes.It really should come with a case bushing. Sun gear/rear planet bushings. Output shaft to input plastic bushing and a front ring gear bushing. Plus a direct drum bushing. Fortunately I have them on hand. But those bushings take a huge amount of wear. And are really the minimum to change on a build.

Great value.
Great price on this kit and it had everything needed to do the job. The most heavily worn bushings (typically) were also in this kit and a an adjustable shift modulator.

Usually buy Summit Kits, but these kit was a good buy since i needed just a few of the gaskets for a valve body replacement.

Mismatched parts, Zero support
Received 1st kit for th350, it had correct clutches and seal but the steel clutches were for a th400. I contacted Amazon they immediately sent a replacement kit. The replacement kit also had the steel for a th400. I was told by Amazon to contact the manufacturer. I tried to call ATP 10 times and got one snotty receptionist who sent me tech support to leave a message. I received no return call. Amazon offered to send another kit but i want willing to wait and get another mis assembled box so I returned both kits and went to summit like I should have in the beginning. Take my advice, don't waste 2 weeks with this junk. I gave 1 star but it deserves nothing.
