Why won’t my transmission go into reverse? A transmission that will not engage Reverse can have a relatively simple cause, such as low fluid or a shift-linkage problem, or a more serious issue involving the valve body, solenoids, hydraulic pressure,…
Why won’t my transmission go into gear? A transmission that will not engage can have several causes, ranging from low or incorrect fluid and a damaged shift linkage to faulty solenoids, valve-body problems, electronic faults, torque-converter issues, or internal transmission…
Why is my transmission slipping? A slipping transmission can be caused by low or leaking fluid, worn internal clutches, faulty solenoids, hydraulic pressure problems, torque-converter issues, or other mechanical and electronic faults. The important point is that slipping is a…
Signs you need a transmission rebuild or replacement usually become noticeable through slipping, delayed engagement, harsh shifting, unusual noises, fluid problems, or a loss of normal gear operation. But a symptom does not automatically mean the entire transmission has failed.…
The best transmission for an LS swap depends on the engine’s power, vehicle weight, intended use, available space, electronics, and budget. The 4L60E, 4L80E, and 6L80E can all work behind an LS engine, but they offer very different combinations of…
4L60E to 4L80E swap projects are common on GM trucks, SUVs, and LS-powered builds where the original transmission no longer fits the vehicle’s power level, intended use, or build plans. The conversion can be straightforward mechanically, but it is not…
4L60E vs 4L80E is one of the most common transmission comparisons in the GM and LS-swap world. Both are electronically controlled four-speed automatics with overdrive, but they were designed around different applications and have significant differences in size, gearing, internal…
6L80E replacement transmission buyers have more to consider than simply finding a six-speed automatic with the right name on the listing. GM used the 6L80 across a wide range of cars, trucks and SUVs, and the transmission evolved throughout its…
4L60E transmission replacement is one of the most widely used GM automatic transmissions, but buying the right replacement is not as simple as matching the name on the transmission. The 4L60E was produced across a wide range of GM cars,…
A 4L80E transmission can be an excellent choice for a GM truck, performance build, or LS swap, but buying the right one requires more than searching for “4L80E” and choosing the cheapest listing. The 4L80E is a longitudinal, rear-wheel-drive, electronically…
