NO LEAK 20601 Gearbox Transmission Stop Leak

I waited until I used this to leave a review but a year on and I still havent used it but it seems good value.Sorry.

I drained some of the oil out to get all the stop leak in as it said ,ran the van for a few days checked to see if it was still leaking and much to my surprise it has stopped. Leaking great

I have only just put in my gearbox so have not really had time to evaluate it's effectiveness yet.

A good bit of kit that has made a noticeable difference

Purchase this as my automatic is leaking, I did think this will work both manual as well, when it arrived it say not for CVT! As I found out it is for oil to work with this as automatic is not an oil more like a fluid. Got send it back!

Excellent​

because not stop leak!! Not work!!

Excellent product, thank you

All I can say is this stuff works I had a 1985 F250 and the power steering area was totally greasy and dirty and leaking fluid from the pump so I bought a remanufactured pump they were so cheap and a new high pressure hose and a new low pressure hose....Only to find out that it was the seal on the steering box so I flushed out all the old fluid and filled up the reservoir full of no leak I started the truck 3 times let it get to operating temperature and on the 3rd time no leak it rejuvenated the seals and they guy I sold it to has not had any leaks either

nul. ce produit n'est pas efficace, a ne pas acheter, toujours des fuites apres usage, a savoir que c etiat de petites fuites

Waste off time

This additive did not work for me (Jeep XJ 4.0L 4 speed automatic with front seal leak at 160K miles).
