check transmission light

[GARY MINKER]

Pete always has good thoughts. If for some reason you have heartburn over the Transynd, check these guys out. http://www.schaefferoil.com/ I run their stuff in everything in my 85PT-40, 2000 Excursion and scooter.

There has been no issues whatsoever with the transmission. You may need to visit an Allison dealer and have them read the 'codes' to get some idea of what's going on. I suppose that the synthetic may have loosened some left over gunk from the old dino-fluid that has subsequently clogged or blocked something inside. To quote from the Transynd brochure: [Natural oils] undergo physical and chemical changes with extended use. Physical changes include sheardown -- permanent viscosity loss. Chemical change results fromoxidation when oxygen combines with oil molecules to produce peroxides and organic acids. The oil thickens over and becomes more acidic. Sludge and varnish deposits erode shift quality and clutch durability and cause increased component wear. quote> I believe that it is recommended that the transmission be "flushed" to remove the dino-oil before converting to a synthetic.

Now the check transmission light comes on while I am driving, goes off at idle, and it won't shift into fourth gear. Any ideas? Dan Williams, 88wb38,Jackson, MS
