i haven't checked the color yet
but hopfully i'll look at her tomarrow or something.
As far as I've heard.. synthetic ATF is bad cause it slips too much and will then wear the tranny out more..
It'* not that'* it is more slippier that'* the problem here. It'* the fact the high mileage transmission has varnish buildup that when combined with a thinner fluid will cause the clutches to slip.

Applications requiring Honda Z-1 transmission fluids
AMSOIL Synthetic Automatic Transmission Fluid exceeds the performance requirements for domestic and foreign automatic transmission fluid applications. AMSOIL ATF provides automatic transmissions, power steering units and hydraulic equipment with excellent lubricating protection and better performance over a wider temperature range than do conventional petroleum fluids.
Resists Oxidation and Thermal Degradation
AMSOIL ATF resists thermal and oxidative degradation up to three to five times longer than conventional transmission fluids do. It protects clutches, planetary gears, valves, pumps and seals from damaging sludge and varnish deposits. AMSOIL ATF helps prevent component overheating and ensures cooler, smoother transmission operation.
Provides Low Temperature Protection
AMSOIL ATF outperforms petroleum fluids in low temperature fluidity. In fact, AMSOIL ATF offers three times the cold temperature fluidity required by current automatic transmission fluid specifications. AMSOIL ATF provides easier starting, faster warm-ups, smoother shifting and improved fuel economy.
AMSOIL ATF provides smooth shifting and long, trouble-free transmission life. In addition, the anti-wear additive package makes AMSOIL ATF an excellent lubricant in other hydraulic systems. In tests designed to measure wear characteristics under severe service and high pressure operating conditions, AMSOIL ATF far exceeds the requirements of hydraulic equipment manufacturers.
Extended Drain Intervals
AMSOIL ATF is formulated for extended drain intervals. Transmissions usually operate under severe service conditions. They are subjected to extensive idling, frequent short trips, cold temperature driving, sustained hot weather driving or trailer towing. When conventional transmission fluid is used, it should be changed every 15,000 to 30,000 miles. AMSOIL ATF should be changed at intervals up to three times longer than the recommendations of the vehicle manufacturer.
AMSOIL Synthetics Automatic Transmission Fluid is completely compatible with other synthetic and petroleum automatic transmission fluids. AMSOIL ATF is a universal, multifunctional fluid and greatly reduces the need for specialized fluid inventories and the possibilities of misapplication.
AMSOIL ATF has an expected fluid life of three times the automatic transmission manufacturer'* recommendations. Drain intervals may be extended indefinitely when fluid analysis is used.
