Mar 10, 2022

Introduction

Welcome to Grafco Electric, your trusted source for automotive electrical solutions. If you're currently facing issues with your 1968 to 1981 automatic transmission not going into reverse or slipping badly, you've come to the right place. In this comprehensive guide, we'll delve into common causes behind these problems and provide effective solutions to help you get back on the road smoothly.

Common Causes

Several factors can contribute to your automatic transmission's inability to engage reverse or experiencing severe slipping. Let's explore some of the most frequent culprits:

1. Transmission Fluid Issues

One common cause of this problem is low or contaminated transmission fluid. Insufficient fluid levels or dirty fluid can prevent proper engagement of the reverse gear or cause excessive slipping. Make sure to check your transmission fluid regularly and perform the necessary fluid changes according to your vehicle's maintenance schedule. Grafco Electric offers top-quality transmission fluid options suitable for your specific vehicle make and model.

2. Failed Reverse Gear

A failed or malfunctioning reverse gear can also lead to these symptoms. The reverse gear is responsible for enabling your vehicle to move backward, and if it becomes damaged or worn out, it may not engage properly. Grafco Electric provides reliable transmission gear replacements using high-quality OEM parts to ensure optimal performance.

3. Faulty Solenoids

Solenoids play a crucial role in controlling the transmission fluid flow within your automatic transmission. If one or more solenoids become faulty, it can disrupt the gear engagement process and result in the described issues. Our experienced technicians at Grafco Electric can diagnose and replace malfunctioning solenoids to restore your transmission's functionality.

4. Torque Converter Problems

A malfunctioning torque converter can also manifest as problems with reverse gear engagement or severe slipping. The torque converter transfers power from the engine to the transmission and can experience issues such as lock-up clutch failure, damaged input shaft, or worn out bearings. Grafco Electric offers professional torque converter repairs and replacements to address these specific challenges.

Solutions

Now that we've covered some common causes, let's explore potential solutions:

1. Fluid Inspection and Replacement

Begin by checking your transmission fluid levels and condition. If low or contaminated, perform a transmission fluid change using the recommended fluid type for your vehicle. Grafco Electric can assist you in selecting high-quality transmission fluids that meet the specific requirements of your 1968 to 1981 automatic transmission.

2. Gear Replacement

If a failed reverse gear is identified during diagnostics, consider replacing it with a new, reliable gear provided by Grafco Electric. Our extensive range of transmission gears ensures a perfect fit and optimal performance for your specific make and model.

3. Solenoid Replacement

If faulty solenoids are the root cause, our skilled technicians will identify the problematic solenoids and replace them with high-quality replacements from our trusted suppliers. This will restore the proper functioning of your automatic transmission's gear engagement.

4. Torque Converter Repair or Replacement
