The 4L60E transmission is widely used in various GM vehicles and requires specific torque specifications for its components, especially the torque converter bolts. This information is crucial for automotive technicians and DIY enthusiasts who are working on transmission installations or repairs.

Torque Specifications for 4L60E Torque Converter Bolts

When installing the torque converter on a 4L60E transmission, it is essential to adhere to the correct torque specifications to ensure proper operation and prevent damage. Here are the key torque specs:

  • Torque Converter to Flexplate Bolts: 46 lb-ft (pound-feet)
  • Torque Converter Cover Bolt: 89 lb-in (inch-pounds)
  • Converter Housing to Case Screw: 48-55 lb-ft

These specifications are vital to ensure that the converter is securely fastened without risking over-tightening, which can lead to component failure or damage.

Installation Tips

  • Use Thread Locking Compound: It is recommended to apply a thread locking compound, such as Loctite, on the torque converter bolts to prevent loosening due to vibrations.

  • Check Bolt Length: When using aftermarket bolts, ensure they are of appropriate length. Shorter bolts may not engage adequately, leading to potential issues.

  • Proper Seating: Before tightening the bolts, ensure that the torque converter is fully seated against the flexplate. This can often be confirmed by rotating the converter while pushing it towards the transmission.
