NO LEAK 20601 Transmission Stop Leak, 16 Fl oz. , Red

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

I use it all the time on my old cars and recommend it for slow leaks. it's the only brand that does what it say, period. and it stops the leaks WITHOUT messing up or gumming up the engine, transmission or power steering units.

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

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

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!

Give 4 star as not been in long but seems to be working

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
