How many check balls are in a 700r4 transmission?
Total, there are nine check balls.
Where do the check balls go in a 4l60e transmission?
The one remaining check ball is placed on the CASE side of the separator plate right next to the 3-4 accumulator bore.
What is valve body in automatic transmission?
The valve body is the control center of the automatic transmission. It contains a maze of channels and passages that direct hydraulic fluid to the numerous valves which then activate the appropriate clutch pack or band servo to smoothly shift to the appropriate gear for each driving situation.
What do transmission check balls do?
Inside the valve body of the transmission, there are different types of valves that direct fluid through the unit. Fluid pressure causes a check ball that sits in a pocket to block and unblock on orifice that fluid is flowing through or trying to flow through. This controls the timing and redirection of fluid flow.

How many check balls does a 4l60e have?
the 4l60e has 10 check balls.
How does a valve body go bad?
When the lubricant used becomes worn out or leaks out, the metal parts of the transmission valve body rub against each other and wear out, causing tiny metal pieces to find their way into the transmission fluid. The effect of this is that the gears may stick and in turn fail to work as required.
How much does it cost to replace a valve body?
When something happens in the valve body – a leak, an electrical fault, or a crack – it’s best to change the whole thing. The valve body assembly will be in the vicinity of $200 to $500, and the labor to replace it will be around $500 or so. Expect around $1,000 to get you back up and running.
How big are the checkballs on a Toyota A340E?
There are two large checkballs in the valve body; they’re 6.35 mm (0.250”). The rest of the checkballs are 5.54 mm (0.218”). Refer to ATRA bulletin #870 for more checkball configurations for this transmission. Once you have the right informa- tion, reassembling the valve body is a snap.
When did the Toyota A340E valve body change?
The major changes to the A340E valve body took place in 2000, with the introduction of Toyota’s V8. One of the changes was the use of a pressure con- trol solenoid. The V6 and 4-cylinder models still use a TV cable. The valve body that we’ll look at is from a 2001 Toyota Tundra with a 4.7 engine.
How to find the valve body layout in sonnax?
Look up make and unit, or search all layouts. Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. Each layout:
How can I Check my valve body plate?
1. Clean all parts in solvent. Dry with compressed air. Ensure all valve body passages are clear. Ensure strainers are not damaged or clogged. Inspect valves for scoring or roughness. 2. Ensure valves slide freely in bores. Inspect valve springs for damage, squareness and collapsed coils. Measure spring free length.
