Granddaddy's Truck

Tbi for the gmt400 is 88 to 95. 96 to 99 is the vortec. 4l60 is the automatic transmission for 1/2 ton. 4l80 is the 3/4 or heavier automatic transmission . If you have standard theres I think 2. One of them is the nv4500 not sure on the second one. Oh and i think thats the heavier duty trans. As for gear ratio look in the glove compartment on the parts rpo codes. You should see something like 342, 373, 410. If not run the vin and you'll get it that way

Thanks!

Been a while since I posted but just wanted to give an update on the truck. Running fine and has been approved for the paint job and it will take place sometime in September. Family friend gave me a killer deal if I brought him the truck completely stripped, so whenever I get the phone call that he’s ready I’ll strip it down and trailer it to him. I’ll be sure to include pictures of it in my next update. Hope y’all are doing well

Just wanted to poke around and ask any of y’all. Does a 305/75/16 tire exist anywhere? I’ve been looking for those on google and it keeps correcting the 75 to 70 which obviously wouldn’t fit when I definitely type 75. Issue is I’ve already got about 60% tread on the yokos I got and am just looking around for what I can get this time next year. I want nitto mud grapps in the worst way (yes I know I’ll probably be making a mistake) but just can’t find any tire in that size

No such 305 75 16 tire size exists.
However, 315 75 16's do!. I know, I have 8 of them!

^^Correct, only a 305/70r16 tire exists.

Get the 305 mud grapps. I've probably had 5 sets of them mostly in 35x12.50x17 and other than being loud they are a good tire. Keep the air right and rotated and they wear even and I've got 40k miles out of a couple sets. My 98 is getting the 315s pretty soon when I replace the bfgs.

My dad had a set of those mud grapplers on his K20 before he sold it and holy s h i t those were loud tires. I'm sure they'd do well in the mud though.

What’s going on everybody, it’s been a minute. Finally dropped the truck off for paint about 2 weeks ago and he will have it at least another 2 weeks. Can’t wait to have her back. After that is some interior stuff and some exhaust over the summer. I also had a question that I guarantee someone in here has experienced before. When I shift gears (5 speed manual), I hear a loud clunk sound in the rear end, and sometimes when I take off it clicks rapidly in gears 1-4. Does anyone know what that is and how to fix it? Thanks. Hope y’all are doing well

Good to see you checkin in. Look forward to seeing pictures when it's painted.

I’d be careful about getting hopes up about certain types of tires, the way things are going. I could be wrong, but I think it’s gonna be really hard to get what we want exactly. My brothers is having trouble with getting the right tires for his ram 2500.
