Will adding seafoam TT-16 to my trans. fluid make for to much liquid volune ?

It is never a good idea to overfill an A/T, just siphon or drain an amount of trans fluid equal to the amount of Trans Tune your adding. If using as a filter change flush I add 1/2 can, drive for a few miles, then drop pan change fluid and filter,then add second half of can with proper amount of recommended fluid. I have followed that procedure for years on various makes and have had no problems. Hope this answer helps.

Should I use this in a new (2015) F-150 as a part of regular maintenance or wait till I notice "problems"?

Many (almost all new cars) can only access the trans fluid from under the car. When you get your oil changed, you can ask the service station to put it in. No guarantee they will actually do it. If you can access your fluid from under the hood, it's great to add it as regular maintenance but not needed so soon.

Is it ok to put it in my 2012 mercedes benz glk 350 4matic suv..how and where should it be added in the transmission??? plz lemme know

your transmission is sealed meaning you must break the tab off the cap at the fill tube located at the top back of the engine. then you need to buy a dip stick for your car and measure your fluid. Its reported that MB transmissions are critical about quantity of fluid level {not to much and not too little}. Once that's all performed TT16 can be added per their instructions. Hope this helps

Does this product have a benefit for manual transmissions? Can I use it in a manual ...

Should be unnecessary. Manual transmissions are much simpler and don't suffer the same problems. If you would go to the trouble of adding this you might as well just open the drain plug and change your transmission oil. Do that every 80,000 miles and you should be in good shape.

Effective

Used on two 13 year old vehicles. Power steering noise reduced and steering became free. Am changing the power steering oil after 200 kms of running. Will add a fresh batch of this oil to keep the system in shape.

Buy it, it works.

Ordered this to try and "clean up and free up stuck/dirty solenoids" in a BMW transmission. Added this to the transmission and drove it around the neighborhood to get the fluid flowing. THIS STUFF WORKS!!! The transmission has 166k miles and fluid has never been changed. The transmission would not downshift when going up hills and would give a code for the solenoid. I bought this to clean up the transmission and free any stuck parts before doing a fluid change and this stuff did the job and then some. Transmission is shifting great and acts like a new transmission. Great value for a product that works.

Steering hydraulics cleaner.

I used the product with the aim of cleaning up my steering rack hydraulics. It made a slight improvement to the racks workability. It was my cheap option before choosing to replace the rack.

Accord 99

Los Honda Accord 6ta generación son famosos por su transmisión que se deteriora muy rápido. La mía ya pateaba fuerte y no metía segunda. Le hice el cambio de aceite junto con este aditivo (siguiendo las instrucciones) y el carro funcionó perfectamente 5 minutos después de dejarlo trabajando. Volvieron a. Entrar los cambios como se supone debe trabajar la transmisión!

Really effective hydraulic system additive. Quality USA made product.

Really did the business on my 33 year old PS system. Steering became heavy & notchy on direction change (possible sticky/partially blocked valve body?) so flushed the system out, added new fluid then poured in this additive. Smooth, quiet operation within 10 mins, with more steering assistance in the 12-years I've had the car. Worked a treat for me!
