Service bulletin 08-08-110-010 describes the conversion and (thanks to the Internet Archive) the text is available here. Here's the list of parts I used:
GM Description 25864433 Floor Mats, Carpet, Front (ebony) 10351595 Hook, Front Floor Panel Carpet
My strategy was to use masking tape and a sharpie to mark the position of the old mats and then cut slits in the carpet for each hook such that the new mats would end up in the same place.
Notes:
You need two hooks for the left/driver's side and one for the right/passenger.
The location of the right/passenger side hook moved in late 2013.
When installed the hooks cover the old stud holes in the carpet.
Original | Replacement |
The original solenoid was much larger than the replacement (GM 19178634). The factory service manual calls for a Kent Moore J-41099 (which is a fairly deep 34mm socket) which I didn't have at the time but honestly I'm not convinced there is a enough room to use a ratchet with the transmission still in the car so ultimately I found it easier to remove the entire assembly and replace the solenoid on the bench using a large crescent wrench. I was able to torque the new solenoid in with a 27mm deep socket.
After removal I tested the original solenoid with a suitable 12V power supply; I found that it frequently would stick in the retracted position, accounting for the symptoms I observed.
My T56 transmission has leaked a tiny amount of ATF over the past few years. Googling showed one possible source is the skip shift (aka CAGS) solenoid. Apparently the original design starts to leak internally. One way to solve this is to replace the solenoid with a plug (e.g. the one sold by ICT Billet) but if you do that you'll need to plug an aftermarket skip shift eliminator into the harness or else you'll get an engine check light. But since I use the CAGS LED Fuse method I need the solenoid to be present.
Original and Replacement |
When I removed the old solenoid I found ATF in the connector. Given it has a seal it was pretty obvious that the leak was internal to the solenoid.
Just like the reverse lockout solenoid, the original takes a 34mm deep socket and the replacement a 27mm.
It's listed in TSB (#99-08-64-016A) as being one of the two products that should be periodically applied to weatherstrip surfaces. A cheaper option is dielectric silicone grease (GM 12345579 or equivalent).
When the radio does not receive any frames on the J1850 bus from the XM module it will remove the soft button for XM bands.
