How Much Does Flushing a Transmission Cost?

 
average costStandard Fluid Change: $75-$150high costPower Flush: $125-$300
post Post   Comments (89)  

In a standard transmission fluid change (also called a transmission service), the transmission oil pan is drained and refilled, the engine is run and then the fluid (oil) is topped off as needed. In a power flush, a machine uses pressure to pump new fluid into the running transmission while the old fluid drains out (a practice some vehicle manufacturers caution against). These are separate procedures, but either one might be referred to as flushing a transmission.

Typical costs:

  • Expect to pay $75-$150 or more for a standard transmission fluid change. This typically includes replacing the filter, and generally uses about 5-7 quarts of fluid. It does not replace the 5-8 or more quarts of fluid trapped in the torque converter, so old fluid will mix with new. Some experts recommend draining and refilling three times, so the fluid is completely changed.
  • Flushing a transmission with a pressurized machine can cost $125-$300 or more, and may include pushing a special cleaning compound through the system. The power flush process typically replaces all of the transmission fluid, and can require 12-22 or more quarts.
  • Prices vary depending on the procedures used; the make and model of vehicle; and whether the work is done at a standard repair shop (either independent or part of a chain) or at a car dealership -- and prices can be considerably higher for luxury or exotic vehicles. For example, CostHelper readers report paying $90-$378 for a transmission flush at a oil-and-lube or auto repair shop, at an average cost of $160; or $77-$295 at dealerships, at an average cost of $205; and a CostHelper reader in Nevada reported being charged $766 for a transmission fluid change on a Lamborghini Diablo.

What should be included:
  • For a standard transmission drain or service, a drain plug in the transmission is removed and the fluid is allowed to flow out into a pan. CarReality offers a how-to video[1] .
  • For a power flush, typically the machine is connected to the transmission, and the vehicle is left running during the flushing process; the exact process will vary depending on the machine used. Machine manufacturer Wynn's has a video demonstration of a flushing machine[2] .
  • Debris dislodged by a power flush sometimes clogs the transmission or the pressure might damage the seals (although not all flush machines use high pressure). Many manufacturers recommend draining and replacing the transmission fluid periodically, but do not recommend a power transmission flush. For example, Honda[3] warns against transmission flushing, saying there is no benefit to a power flush and it could void the warranty.
Discounts:
  • Do-it-yourselfers can save money by draining and replacing their vehicle's transmission fluid. AutoMD.com provides general how-to instructions[4] and estimates the project as moderately difficult. The main cost is the quarts of new transmission oil. CostHelper readers report paying $40-$175 for do-it-yourself supplies, with an average of $90.
Shopping for flushing a transmission:
  • Always check the maintenance schedule listed in the owners' manual before ordering a transmission service or flush; some shops may recommend these procedures before they are needed. Consumer Reports lists transmission flushes among the "extra and often unnecessary procedures"[5] that might be considered auto-repair rip-offs.
  • The National Institute for Automotive Service Excellence provides a searchable directory[6] of certified shops.
  • Consumer Reports lists tips for finding a good mechanic[7] .

Posted by: Gary Jennings in Baltimore, MD.Posted: June 2nd, 2016 01:06PM
A transmission flush does not change all the fluid and it is not a power flush in the way you think. The most used procedure simply supplies fluid to a disconnected cooler line at the radiator & when the engine is started, the transmission's pump draws new fluid into the transmission where it mixes with the old and then is expelled via the 2nd cooler line. It has estimated a typical flush replaces 63% of the old fluid. Naturally the more new fluid that is used in the flushing process the greater the percentage that is replaced, but that gets very expensive and the benefit is questionable.

My transmission pan was leaking. I'd never changed the filter on this transmission so I figured it was about time. I pulled the transmission pan and found there was no gasket, just gobs and gobs of silicone and overtightened bolts. Cerritos Dodge last touched the transmission for warranty work years ago and some Butcher did the gobs of silicone and overtightening of bolts.

Bought trans filter, gasket and trans fluid. Already had the silicone to lightly coat the pan gasket. I torqued the pan bolts to factory specs. Did the job in late July and still dry, no leaks.

It was $24 for the transmission filter and $31 for the three gallons of tranny fluid. The pan gasket is reusable and I had the hi-temp silicone.
It's messy DIY because tranny pans generally don't have a drain plug, so all the bolts have to be loosened and the fluid eased out before taking the pan down to get to the filter.
