ICT Billet 4l60e Bell Housing to Transmission Case 8 Bolts Replace Torx Replacement Set Kit T56 LS1 LM7 LR4 LQ4 LS6 L59 LQ9 LM4 L33 Made in America Bell housing 551684

Ordered and installed these in place of the original torx+ bolts GM used on the 4L60 transmission. They fit great and are excellent quality. The torque converter does not touch them when everything is fully assembled and bolted up, the torque converter will only touch the head of these bolts when it is slid as far as mechanically possible onto the transmission input shaft, this is not an issue once the torque converter is bolted to the flywheel!

Great bolts for a 4L60, the star pattern ones require a special bit to remove, my torx bits bounced off a little cheewing up some, had to cut them to remove, I know for a fact this replacement set won’t be having that problem should I ever need to remove the bell housing again.

Worked perfectly. Wanted normal bolts instead of the tp55 bolts since one of them were stripped and had to rattle loose with air hammer. Fitment is great even with FTI 3k stall converter.

As you might know, GM' design for the torx bolts that connect the bell housing cover to the 4L60E is atrocious. Good luck getting the old ones out, lol. I used a drill with a hardened metal bit and then used a cutting wheel to flatten the heads. Once the cover was off, I used vice-grips to get the remaining studs out. However, once that's done, these bolts are just what the doctor ordered.

During the transmission removal, some of the case bolts were lost. I could not find a suitable replacement locally. These bolts are an exact replacement high-strength with a Torx head, and are easy to get back into position when using a long extension to access the upper transmission case bolts.

Just what I ordered very fast shipping....no complaints here ... very happy..thanks AmazonRegards Kevin

These bolts worked like they were intended they do not rub the torque converter. So far no issues used on a 4L60E mated to a 5.3L in a 2004 trailblazer.

I bought these to replace several stripped T-50+ fasteners(had to weld a nut to one to remove it!) in a 2001 Tahoe with an 11.81” converter. They make contact with the converter when trying to fully seat the converter. I ended up using two of these for the two bolts locations that are further out from the center. Didn’t want to risk the others as I had to shim the converter to get proper spacing.
