[QUOTE="ToMang07, post: 1448810, member: 4800"] [B][FONT="Times New Roman"][SIZE="3"]So Thursday plowing I overheated the transmission. Didn't puke, but when i noticed it I parked it for an hour and let it cool. (Actual temp unknown since GS gauge is broke.) Did pop the "overheated" code. Fast forward to yesterday, driving to work unloaded truck was driving normal without issues, went to pass somebody, and all of a sudden it started vibrating, bad, gets worse when the torque converter locks in, and it is a low stall TC. (1300 IIRC) Transmission was "rebuilt" but a bunch of jackasses who supposedly did a mild build on it, ie upgraded clutch packs, shift kit, etc. My brothers F150 is back at the same shop for the 4th time getting it's 3rd transmission, been there for MONTHS, and I have 0 confidence in this shop to fix or honor their warranty, especially not in a speedy manor. Ran an injector CCT and it never really runs it, pops #1 and stops. Ran the KOER test and 2,7 and 8 popped. When running a buzz test everything sounds normal. I forgot to write codes down (in mostly a rage) and will have to look them up on my laptop tomorrow or tonight. Idle is VERY rough, whole truck shakes like a cammed out big block, sounds almost like a dead cylinder on the drivers side. Is this more likely an injector issue or transmission? The vibration smooths out around 2k RPMs, and gets very bad at low RPMs, (Idle-1500) [/SIZE][/FONT][/B] [/QUOTE]
