However the exact cost of automatic transmission diagnostic will depend on where you take it. Whilst the average cost of an automatic gearbox repair is around a more costly figure of £550, the average cost of an automatic transmission diagnostic is £224.
Automatic transmission diagnostic average costs and prices However, repairing or replacing an automatic transmission is a costly job, so it is better to keep to the schedule of the recommended automatic fluid change intervals. Some manufacturers don’t recommend the change as frequently as they suggest flushing it only every 100,000 miles and others don’t mention transmission flushes at all.Īutomatic transmissions are susceptible to damage over time, and sometimes a car owner will find, no amount of transmission fluid changes can prevent that. Most manufacturers recommend a transmission flush and transmission fluid change every 30,000 miles or every 2 years. It also helps valve operation, brake band friction, torque conversion as well as gear lubrication. So, all in all, it has a very important job of keeping things running smoothly within the transmission system. Its job is to lubricate mechanical parts, maintain fluid pressure, cooling, preventing oxidation, conditioning the gasket, and preventing rust. (On both sides of the hyphen, a higher number means a higher viscosity.) What makes this type of oil so flexible? It’s the polymers-particles that expand as the oil heats up and slow down the rate at which the oil thins as it gets hotter.When we consider the functions of the transmission system, the transmission fluid is a crucial component of the system's operation. The number after the hyphen is the viscosity at 210☏, the standard temperature of an operating engine. The number preceding the W stands for “winter” or “woolen-underwear season,” which reflects how the oil flows when starting an engine on a cold day.
When you see a viscosity grade on a bottle of multi-grade motor oil-say, 10W-30-there are two numbers to consider. There was a time when people who live in four-season climates would use one oil with a higher viscosity during the warm months and another during the cold months, but multi-grade motor oils solve that problem by working efficiently in both conditions. Lower-viscosity oils work better at lower temperatures since they don’t need to be heated to flow, but they generally offer less protection against wear. Higher-viscosity oils are most appropriate for cars that operate at higher temperatures or carry heavier loads. Like most liquids, when oil is cooler it’s more viscous (that is, slower-flowing), and when it’s warmer it’s less viscous. But for those who are interested or who have to make elevator conversation with a talking car, there are a few basic principles to consider.

Fortunately, auto manufacturers specify what viscosity level is best for their vehicles, so most drivers never have to spend much time pondering this subject. Factors such as varying starting and running temperatures, an aging car, or heavy loads on board can all affect how motor oil performs. But there are many things that can keep oil from staying on top of its workload, and that’s where viscosity comes into play. Whenever a vehicle is in motion, engine oil has a lot of work to do: reducing friction between moving parts, keeping the engine from overheating, preventing components from prematurely wearing down. Motor-Oil Viscosity: A Slippery Subject The oil viscosity your car needs is usually determined by your car’s manufacturer, but is there ever a reason to switch? Groupon sought out the answer. $110 for a transmission-fluid exchange with filter gasket ($220 value) $85 for three oil-change packages ($194.94 value)
