Last week I ordered some new parts to put on the Suburban, and some of them are already here! Summit had an insane turnaround of right about a day to get me most of the parts I ordered. I bought an Autometer Z-Series tach, an Autometer 3-gauge panel, a TCI deep transmission pan, and a Firestone airbag kit! Everything but the airbag kit is in; they're estimating another 2 weeks for the airbags because they're special-order from Firestone. I am so excited to have ordered these parts. Here they are: And here's some of the TCI pan. It's for the 700R4 in the Suburban, and lemme tell you, it's MASSIVE and HEAVY, especially for aluminum. It must weigh 5-10 pounds! It's also considerably larger than I imagined in my mind's eye. The pan is also considerably deeper than the factory pan, but was designed to clear the transmission crossmember that passes under the last 2 inches or so of the pan. It also has a drain plug that the factory pan doesn't have and provisions for a transmission temperature sender. Additionally, the temp sender port seems to be in a different spot than what I saw i the pictures when I ordered it. The pictures indicated the sender would be on the side of the pan which is fine, but it's actually on the back, where the sender can be protected by the transmission crossmember, so kudos to TCI for thinking about that. The description claims that it works with stock filters and has raised sections in the pan to hold the filter up, but then TCI specifies 2 part numbers for filters in the instructions. I still need to research whether these are deep filters, or stock height; I'm hoping the latter. The tach is a 2-1/16" Autometer Z-series tach that goes up to 5000 RPM. I could have gotten a higher-range tach, but I don't ever expect to break 4000 RPMs in the truck, so why have that extra range. It should also give me better resolution on the exact RPM I'm running at since the scale is dedicated to less RPMs. It should hook up to a white wire coming off the coil helpfully installed by Chevy even though Chevy trucks during that time period only VERY VERY VERY rarely had tachs from the factory. Works for me. I'm hoping to get all this installed sometime during the week or next weekend. The weather's not looking too great this week so it might get pushed back more. Oh how I wish I had a shop I could drive the truck into... So look forward to write-ups on these mods and more in the future!
