Helped my Chevy truck greatly.
pUT THIS IN MY 1999 Chevy Silerado. Was startingto develop a hard shift from 1st to 2nd. Put it in really didn't feel much of a difference. But after 2 or 3 days of driving. roughly around 60 to 70 miles. Truck is shifting some much better now. WOuld buy it again.

*5/5 estrellas - ¡El salvador de mi transmisión!* Estoy muy satisfecho con el pomo de aditivo para la transmisión que compré en esta tienda. Mi transmisión estaba empezando a dar problemas, pero después de usar este aditivo, ha vuelto a funcionar como nueva. La calidad del producto es excelente y el precio es muy razonable.Si estás experimentando problemas con tu transmisión, te recomiendo probar este aditivo al 100%. Es una solución efectiva y económica que te ahorrará dinero y dolores de cabeza. ¡No te arrepentirás!

The Dynaflow transmission in my 1953 Buick has been sub par for a while, including a leak. The first time I used Barr's transmission treatment the improvement was staggering. No slippage and close to perfect shifting. A little early to tell if leakage has been reduced but I will report later. I have another bottle ready to re-treat as needed and will reorder to have some on hand. At this stage I am no longer considering having the transmission rebuilt, saving a few thousand dollars!

Wow! I was doubtful when I ordered that this could fix my transmission. I have a clear leak and it causes a heavy gear shift. Within a day of adding to my running vehicle with a funnel through the tranny dipstick slot, the heavy shifts were gone. I have no evidence the leak is still there nor corrected yet, but felt a difference despite me expecting nothing.
