Automatic Transmission Pros
- Ease of use - No need to shift gears makes driving simple and convenient.
- Works better in traffic - Automatically changes gears in congested driving conditions.
- Appeal for resale - Most buyers prefer automatics so they have a higher resale value.
- Improved technology - Modern automatics have more gears to optimize efficiency and performance.
Automatic Transmission Cons
- Reduced fuel economy - Auto gear shifting is less efficient leading to 10-15% lower mpg.
- Higher maintenance costs - More fluids to change and a complex design means pricier repairs.
- Less driver control - The computer dictates gear changes rather than the driver.
- Lower towing capacity - Automatics have torque converter slippage so can't haul as much.
Real World Examples
The 2021 Toyota Corolla gets 32 mpg city/41 highway with the manual transmission. The automatic version is rated at 31/40 mpg. Over 15,000 miles of mixed driving, that can add up to $75 in fuel savings with the manual. However the convenience of an automatic can be worthwhile for some drivers despite the slight reduction in fuel economy.
As for maintenance, a clutch replacement may cost $800 compared to $3000 for a transmission overhaul. But if you practice good driving techniques, a manual transmission can last upwards of 100,000 miles without major repairs.
The Final Verdict
Ultimately the choice depends on your specific needs and preferences. If fuel efficiency and performance matter most, a manual is likely the way to go. But if you want sheer ease of driving especially in heavy traffic, an automatic would be ideal. Test drive both options carefully before making your decision.

Getting More Horsepower to the Wheels with a Tuned Drivetrain
Engine mods can dramatically increase horsepower, but inefficient drivetrain components sap that extra power before it reaches the wheels. Here's how to optimize your drivetrain to transmit as much horsepower as possible to the pavement.
Lower Final Drive Ratio
A lower (numerically higher) final drive ratio lessens drivetrain loss off-the-line to maximize acceleration.
Shorter Gears
Reducing the gear ratios in the transmission and differential decreases power loss through the system allowing more hp to reach the wheels.
Lightweight Flywheel
A lightweight flywheel has less rotational inertia so the crank can accelerate easier translating to quicker rpm increases.
Performance Clutch
Upgraded high friction discs provide solid engagement to handle the torque without slippage.
Aluminum Driveshaft
Replacing a heavy steel driveshaft with lightweight aluminum reduces rotational mass and power loss.
Synthetic Lubricants
Reduced friction synthetic gear oil and differential fluid equals less internal power consumption.
Results
On a 300 hp car, an optimized drivetrain could gain:
- Lower final drive - 5 hp gain
- Shorter gears - 8 hp gain
- Lightweight flywheel - 3 hp gain
- Performance clutch - 4 hp gain
- Aluminum driveshaft - 2 hp gain
- Synthetics - 3 hp gain
That's potentially 25 more horsepower making it to the wheels!
