A little patience goes a long ways

Got this kit yesterday and installed it 12/23/23. Everything was fine... except that with my vehicle the hoses need too be swapped. Refer to the online directions. Another pro tip... Orings don't stay on the fitting, they go under the washers (patience or paying attention might have helped the first time). There are a couple of good YouTube videos if you get stuck. Other than that the kit was very good, I had zero issues with the fittings, just take your time.

Made very cheap

Lines are thin rubber. Fittings are a very soft material and strip extremely easy. To the point of them not sealing because you cant get them tight enough. 10 out of10 do not reccomend. Coming from a real mechanic. Buy KBD lines. There 100% quality and worth your money.

Easy install just wish i did not have to look up the instructions.

Fitting are cheap and over sized.

Lines are great but the cheap fittings they send are over sized. So when you install them it cuts the threads and you have metal fillings inside. So you will need to pull them back out and get all that out of there before running the metal fillings through your Transmission. They could afford to send better fittings or just the right size fittings whit the amount these cost.
