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.

Some fixes in a can WORK

Have a dodge 2500 that won't shift past second gear? Have a 99 Ford F-150 that slips in between gears? Have an 07 Maxima with a shuttering torque converter? Buy this and erase all those issues. I did. Works great and is getting harder to find because it actually works wonders.

Real Deal. Pretty awesome stuff

My Dad swears by this. He had a Ford Tempo would drop into neutral (torque converter slipping) at red lights until you rev to 3k rpm then jump into gear chirping tires. And a Dodge caravan that trans slipped. Both vehicles he would add 1 quart and they would be fine from 1, 3, 6 months. Then slip again eventually he would add another quart. Sounds ridiculous but if you aren't ready to drop the $ and the transmission, or scrap the car yet. This Stuff Works.

works

I got this to make the steering wheel in my old civic hatchback smoother. I pumped out a bit of fluid from the power steering tank, added half a bottle of this stuff, ran the car 20 minutes while moving the steering wheel back and forth. Then I drove my car about 30 minutes and topped off the power steering fluid with 'lucas power steering fluid+conditioners'. The wheel moved so much better, so I'm happy. I docked a star because when I pulled the white tab off the mouth of the bottle, a bunch of purple fluid came out and got all over my hand that was holding the bottle. Made me mad, especially because my toddler was at my hip on the other side. Not really an issue with functionality of the fluid, just pressure in the bottle, I guess. So, wear gloves and open somewhere that you're ok with potentially getting dirty
