Purely remarkable endurance

Conventional transmission fluids have performance additives blended in friction modifiers, anti-wear agents, antioxidants, dispersants, detergents, rust/corrosion inhibitors, seal swell agents, anti-formants and more. But, because the base fluid is petroleum, conventional fluids do not provide the thermal resistance of TranSynd. With extended use, petroleum-based fluids react to oxidation much faster and more detrimentally, overwhelming the effectiveness of the dispersants and detergents. The oil thickens and becomes more acidic. Mechanical stress leads to shear, resulting in permanent viscosity loss. Thinner oil means less lubrication. Sludge and varnish deposits erode shift quality and clutch durability, causing increased component wear.

TranSynd, on the other hand, is formulated from pure synthetic lubricants with inherent thermal and viscosity advantages. Performance additives are then tailored to the unique molecular structure and excellent antioxidant properties, resulting in a lubricant that is far more chemically and physically stable than other oils and virtually impervious to shear.

Nothing protects better

The fluid in an Allison Automatic is more than just a lubricant; its a critical component of the transmission. It literally transmits energy between the engine and driveshaft, removes heat, lubricates, enhances seals, protects, and acts to maintain constant friction properties between friction plates and reaction plates. TranSynd fulfills all of these functions far better than conventional automatic transmission fluids.

Liquid asset

By greatly extending drain intervals, TranSynd helps lower the costs for maintenance and downtime. You save on the cost of transmission fluid, replacement filters, the disposal and liability of used fluid. Most importantly, you benefit from reduced wear, better performance and longer service life from your Allison Automatic. Bottom line: the superior lubricating protection of TranSynd results in even greater productivity and lower operating expenses.

Allison developed, Allison recommended, Allison approved!

Like the title says, is there anything more you need to know? Run this in your Allison transmission to know you have the absolute best fluid available for your expensive diesel transmission. I ran this through my trans along with a new deep pan, filter, lock, and TransGo Jr. trans kit.

Great Place To buy Transynd Transmission Fluid, Plus Alot More !!!

Who doesnt use TRANSYND? I mean would you drink puddle water? Nah. Treat your trans to the best, expect great things. Buy it from someone else? I mean if you're into that, but why spend more. Merchant has the best price and quick and easy shipping. Don't hesitate, click add to cart and pay. Thank me later

Ordered and the package came quickly and most importantly secured inside the box. There was enough packing to keep the bottles safe along with the extra filters I ordered at the same time. Price was also better than locally available here.

My 2005 Allison was replaced under warranty in 2008. There’s no telling whether to use dexton iii or vi. Transynd is perfect. Pricey, but my Allison is worth it. Merchant had the best delivered price I could find.
