Need Help Finding 4L60E Bell Housing Bolts

Questions and Support
1

I’ve been working on some maintenance for my Chevrolet and came across the 4L60E transmission. I’m in the process of reinstallation and need to secure the bell housing properly. However, I’ve hit a bit of a snag when it comes to the specific bolts needed for this part of the installation.

Questions I Have:

  • What are the specs for the 4L60E bell housing bolts? Are there specific lengths and thread sizes I should be aware of?
  • Where can I buy them? Any recommended online retailers or local auto parts stores that typically carry these bolts?
  • Do I need anything special for installation? Like a torque spec or specific technique?

I’ve read some forums and guides, but they seem to vary in details, and I want to make sure I get this right. If anyone could point me in the right direction or share their experience, I’d really appreciate it. Knowing the exact requirements is so important for a secure fit, especially with something as critical as a transmission.

Thanks in advance for any insights you can provide!

I’m looking for the correct specifications for the 4L60E bell housing bolts too! If I remember correctly, they are 10mm x 1.5 thread size, around 30mm long. Can anyone confirm that?

Yes, you’re on the right track! The 4L60E bolts typically use a grade 8 material for better durability. You definitely want them tight but not overtightened!

I’ve found that using stainless steel bolts helps with corrosion resistance. Just be cautious with the torque specifications!

In my experience, using a thread locker on these bolts can be very useful for preventing loosening over time. Anyone else tried this?
