If your vehicle suddenly hesitates or slips when accelerating from a stop, don't assume it's just low oil; that erratic behavior often indicates a deeper issue with internal transmission pressure or t…
A sequential transmission unit operates by mechanically connecting or disconnecting power through a fixed set of gear ratios, using an automated control system—often hydraulic and electronic—to select…
If you are finding yourself trying to diagnose an automatic transmission issue based only on what the owner’s manual suggests, chances are you are misunderstanding how fluid condition relates to inter…
If you are swapping an older manual unit into a modern, higher-torque vehicle, selecting a transmission requires assessing more than just the gear ratio; you must determine if the physical size and mo…
For understanding AISIN transmissions, you are faced with two approaches: first, reading a general manual that describes automatic transmission function, which is fine if you just want to know *what i…
An automatic transmission fundamentally manages torque conversion and gear selection by using hydraulic fluid pressure to actuate internal clutches and bands, allowing a vehicle to shift gears smoothl…
When replacing a transmission, the most common error is assuming that any unit labeled for your vehicle will work; in reality, transmissions are incredibly specific, and failing to verify the exact mo…
Generally, if you have an automatic transmission that shifts smoothly and you hear a distinct "whirr" sound when accelerating at low speed without feeling any gear change, you likely have a Continuous…
A continuously variable transmission (CVT) does not use fixed gears; instead, it uses two variable-diameter pulleys connected by a belt or chain to achieve an infinite number of gear ratios between hi…

When you find yourself needing to maneuver a heavy vocational truck through a muddy job site—say, moving a specialized piece of construction equipment that requires maximum torque at low speeds—you ar…
The 4L60E is a robust, electronically controlled automatic transmission designed to offer smooth, reliable shifting across a wide range of applications; understanding its primary components—including …
