Prolong Super LubricantsPSL15000 Transmission Treatment, 8 oz

Ok so 1stly, not one to make reviews on stuff but I wanted to share my experience to potentially help anyone on the fence or curious about prolong products especially the transmission additive.So if you have a 09 or newer hemi ram 1500 laramie, the digital gauge cluster gives you oil temp, oil pressure, coolant temp & transmission temperature. So the truck with 180k mi on it at the time, me & dear old dad were headed on a adventure to collect car 2 hours away (astoria or to hillsboro or, hwy 26, from sea level to 1500ft & back down other side). While headed to pick up tow dolly (nothing in tow or in the bed) the trans temp was reading the usual 170 degrees +/-.As we pick up the dolly, I add the trans additive & check all fluids & tire pressure. Hook up & hit the road.While climbing the "mountain pass" I decide to look at trans temp, 130+/- degrees. Whoa, that's noticeably low for the truck, especially towing a empty dolly uphills for an hour. I figured it was a fluke & it was gonna wear off once we got weight on it.Not quite, even while towing on dead ass flat towing a loaded dolly it was never more 140 degrees, and finally the last push up Bradley (return on hwy 30) & thru knapa or, the most it got was 154 degrees! Uphill towing dolly & car... where before it would REGULARLY crest 205 degrees going up Bradley Hill. Now 50 degrees cooler and being put thru the same paces!And still to the day, having done services & filter replacements & continued prolong additive use, not even on the hottest summer day will it crest over 200 degrees. (184 was the most & just recently while towing dolly loaded with 06 crew cab tundra)There's more I could say about it BUT being a skeptic snake oil suspicious individual myself, this is my experience with real numbers showing improvements.Temperature isn't everything, but we should all know & agree that sustained lower operating temp means less fluid overheating, loosing ability to disperse the heat that's generating, heat that's causing more wear metals to cook off into the fluid & clutch material, that's getting caught in filter, stifling flow limiting atf to get around to do its job & keep it cool & lubricated.

I had taken my manual Veloster in to get a new door after someone hit me in the parking lot. Once I got my car back it shifted terribly. As a side note I believe this was most likely caused by a technician at the auto shop I took my car to either hot running my car or driving it without knowing how to drive a manual transmission. The gear lever was very notchy and in sixth gear I had to slam it to even get it to go into sixth gear. So needless to say I was pretty worried about it. I had heard of prolong in the past and so I bought it and thought might as well give it a try. I put it in my transmission last night and after I got everything button back up a cycled through the gears with my foot on the clutch and then I took it for a quick trip down the highway cycling through all 6 forward gears and reverse. And I noticed an immediate difference now I'm driving it again today and it still feels better I think it feels better than it did last night so it seems like it may continue to improve my shifting experience. I'm very thankful that I tried this product and I suspect you will be thankful as well. As I'm driving right now cycling through the gears I'm noticing no spots where it feels like my lever is getting hung up I noticing no I'm hesitation as I fully engage the gear It feels more like it's getting sucked into place as opposed to having to force it into place

Have 186,000 Mi on a 2007 Ford Ranger 3.0V6 5-speed automatic I maintain vehicle myself I've changed the fluid in Transmission between Mobil 1 and Amsoil fully synthetic 4 times and Transmission filter 4 times added a deeper Transmission pan from 4 wheel drive holds extra quart an has drain plug nice 👏👏👏 much smother shifting an firm after adding prolong Transmission additive to keep it going strong.

04 ram 1500 automatic transmission. I read about someone using prolong in a dodge forum and I tried it as a last resort to fix my hard shifting and disengaging problems and it worked. It shifts very smooth now. I removed 8 oz of trans fluid and poured it in. I will use prolong every time I change my fluid. It’s not a miracle in a bottle but it is very effective

I currently drive a 2015 Honda Accord EX-L V6 coupe (6MT), and most of the gears are really notchy, with 2nd gear crunching and grinding sometimes, and 3rd gear locking me out occasionally at high revs. I plan to add this alongside using AC Delco (GM) Synchromesh friction-modified manual transmission fluid. I’m overfilling to nearly ~3.5+ quarts.With only 2.7-3 qts of non friction-modified OEM and other OEM equivalent Synchromesh fluids, I am still noticing crunching and grinding of 2nd and 3rd gear during cold starts/driving. It takes nearly 12-15+ solid minutes of shifting past 2500-3000 RPM, to get the gearbox and trans to properly warm up to proper operating temps.I will update this once I add it to my current mixture of MTF. I am currently running 2 qts of OEM Honda MTF, and 1 qt of AC Delco Synchromesh friction-modified MTF. I plan to fill the rest of the MT with this Prolong MT/AT additive, as well as topping it off with some OEM equivalent 75w80 GL4 MTF made for brass, like Valvoline, Penzoil, or Quaker State Synchromesh.

I have a 2010 Hyundai Accent with over 150,000 miles on it. My kids kept telling me to trade it in, but after seeing the price of used cars, I decided to get it painted for $400 and bought new tires for $350. When I was looking for oil for vehicles with over 75,000 miles on it, I found Prolong engine treatment. I read the reviews and decided it was okay to invest a little extra in safety for my engine. I actually felt a nice change. When I looked back at the reviews, I found Prolong transmission treatment and used that as well. That was a couple of weeks ago. Since then I have been amazed because you literally can't tell the shift from first to second or second to third even when I just started it. I plan to take care of the car, but with these products I have no doubt I could use it for an additional 75,000 miles.
