It might appear that Dexron VI would therefore be backwards compatible as far back as the older TH350 and TH400 transmissions. The reality is that Dex VI is best only for newer vehicles.
How many quarts does a Turbo 400 transmission take?
You can expect to use between 11 and 12 quarts of fluid in the stock version.
What fluid does a turbo use?
The turbocharger bearing system is lubricated by oil from the engine. The oil is fed under pressure into the bearing housing, through to the journal bearings and thrust system. The oil also acts as a coolant taking away heat generated by the turbine.
What type of ATF fluid do I need?
The easiest way to make sure you’re using the right type of ATF is to check the owner’s manual. It’ll tell you exactly which ATF the manufacturer recommended for your car. You may also find a recommendation on the dipstick. Either is a reasonable resource for determining the right type of fluid for your transmission.

How many gears does a 400 Turbo transmission have?
TH-400 transmissions are three-speed automatics, with a 2.48:1 first gear. Reverse gear is 2.08:1 and third gear is an even 1 to 1. Turbo 400s use three tail shaft lengths; the most preferred units for a GM swap would have the short 4-inch tail shaft.
Does a TH400 have overdrive?
But the TH350 and TH400 three-speed versions (and their two-speed Powerglide cousin) fall short when it comes to highway cruising. The reason for this is the conspicuous lack of an overdrive gear. Back in the late-’60s gas was cheap and highway cruising speeds were lower.
Do Turbos need special oil?
Turbo systems are made up of moving parts which spin at incredibly high speeds, and work under intense heat and pressure. This means that they need a constant flow of quality engine oil to lubricate the compression valve and intake and outlet fans, to reduce wear and help them perform at their best.
What oil is best for turbo cars?
Mobil 1 oils are setting the standard for turbocharged engine performance and protection.
Do Turbos need lubrication?
Lubrication is essential for turbochargers, which rotate at extremely high speeds to boost the engine’s power by forcing more air into the combustion chamber. … The oil has a cooling effect as it passes through the turbocharger hoses.
What happens if you use the wrong transmission fluid?
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Can you put ATF in a CVT transmission?
The most common situation where the wrong transmission fluid is used is in the case of using automatic transmission fluid in place of variable transmission fluid and vice versa. Adding ATF to a to a CVT will eventually result in the death of your transmission.
