46re Shift Linkage Diagram

The 46re shift linkage diagram, also known as the A518, is an automatic transmission developed by Chrysler. It’s an upgrade of the A727 and came with an overdrive unit, making it a four-speed. Considered reliable and heavy-duty, it’s no wonder it was standard-issue in trucks like the Dodge Ram and Dakota. But like any other component of your vehicle, it could face issues. However, understanding its structure and how to tackle these issues can save you time and money on a trip to the mechanic.

What is the 46RE shift linkage diagram, and why does it matter? In simplest terms, it’s the blueprint of your car’s transmission system – specifically, the pathway that your car’s gear shifts take to transmit power from the engine to the wheels. Ensuring the correct functioning and alignment of this linkage is crucial because it guarantees the smooth selection and changing of gears.

A poorly aligned or damaged shift linkage can result in hard shifts, transmission slippage, or even the inability to shift gears at all, effectively immobilizing your vehicle. Thus, understanding this linkage is paramount in maintaining or troubleshooting your car, specifically if it employs the 46RE transmission.

Understanding The 46RE Shift Linkage Diagram

The Basics

Before delving into specifics, it’s essential to have a fundamental understanding of the shift linkage. The shift linkage connects your shift lever to the transmission of your vehicle. It allows the driver to select the gear required – Reverse, Neutral, Drive, Park, and others.

In automatic vehicles like those fitted with the 46RE transmission, the selection of gears mostly happens in the transmission itself rather than the manual process in manual vehicles. If there’s a problem with the shift linkage, you’ll realize it fast enough – your car will resist, or even refuse, to go into gear.

The Nitty Gritty Details

The 46RE linkage diagram consists of few essential parts. Firstly, there’s the shift lever, which you use to select your gear. Connected to this is the shift cable, which transfers the motion of the shift lever to the manual lever shaft – a rod that connects the shift cable to the transmission.

On this shaft, you’ll find the manual lever and the manual lever positon sensor, which notes the position of the lever and informs the Powertrain Control Module (PCM). This PCM then adjusts the gear placing accordingly – effectively changing your car’s gear.

Common Issues and Their Solutions With The 46RE Shift Linkage

Like all other mechanical components, the 46RE shift linkage isn’t immune to issues. Some of these include:

Hard Shifting

This problem usually arises if the shift linkage is out of alignment, resulting in difficulty when changing gears. It can be remediated by:

– Ensuring that the transmission fluid level is sufficient and well maintained.
– Stepping on the brake pedal, shifting the transmission through all gears a few times and then checking the fluid level.
– If the gear lever is loose, tighten it accordingly. If this doesn’t fix the issue, it may be time to replace the shift cable.

Cannot Shift Into Gear

This can have many origins. Still, a common reason is corrosion on the shift linkage, effectively freezing it in place. You could:

– Lubricate the shift linkage components regularly to prevent this corrosion.
– Replace any worn out parts of the shift linkage.
– Check the shift cable for any damage or stretching.

Linkage Is Bouncing or Making Noise

This could be due to stretch or misalignment in the linkage. The steps you can take include:

– Adjusting the shift linkage according to the manufacturer’s instructions.
– If the movement isn’t smooth after adjustment, then replace the shift linkage.
– Regularly maintain the shift linkage components, including lubrication.

Frequently Asked Questions

Q. What are the common symptoms of a faulty shift linkage?

Some common symptoms can include difficulty or inability to shift gears, gears slipping out of place, or a loose or wobbly shift lever.

Q. How often should I replace my shift linkage?

Shift linkages don’t have a specified lifespan. However, signs of a failing one should prompt its replacement.

Final Thoughts

By understanding your 46RE shift linkage diagram, you get to understand how to pinpoint potential issues and possible solutions. It empowers you to be able to tackle minor problems on your own, saving you those trips to your mechanic.

However, remember that understanding how to read a shift linkage diagram is only half the battle: regular maintenance and upkeep of your car, including regular checks and prompt replacements of parts, will keep your car running smoothly and prevent the occurrence of such issues in the first place. And remember – if you’re ever in doubt about what to do, it’s always better to consult a professional.
