    98 Yukon oil pressure on the lower side and mechanical whirring noise?

    Oh ok, yeah maybe on the belt drive. I was thinking the whirring was the chain drive under the cover. Maybe problem with oil pump. I'll check out the pulleys.

    98 Yukon oil pressure on the lower side and mechanical whirring noise?

    Does the 5.7 have the same oil pickup tube gasket common issue as the 5.3s? I ask because my oil pressure is good according to the 10psi + 10psi/1000rpm rule. But it is on the lower side, at or right below 20 at idle and 1000 rpms. At or right below 40 at cruising. A bit over 40 on cold...

    Two issues, coolant res level falling and ps rack leaking...

    Yeah I hear ya on the OEM but I couldn't wait for shipping. I think I even saw the OEM was less than the dorman, at least at one seller I looked at. Heater return was $58 and the heater inlet was $61 + black T was $25.99, 14.99x3 for oreily's dexcool fluid. It wasn't cheap, I can't image what...

    I replaced the Ts at the firewall a while back, I had accidentally broke them trying to put the vortec cover back on. Im sure there's lots of videos on youtube for all this. Time to go to Youtube University... Thanks!

    Yeah I am willing to do all that but not before this trip! lol. It is uncanny how these parts all fail around the same milage. I have noticed that from years of reading here and other forums.

    You guys are tougher than me! Thats for sure. I can't do cold. Dont like too hot inland away from coastal breezes either.

    Two issues, coolant res level falling and ps rack leaking...

    Found it. Its this thing. I haven't driven it since wednesday. It was wet when I started looking with the flashlight. Dried it off with a rag, immediately wet again under no pressure. Started engine and it ran down in a thin little stream and saw it drip off the bottom. The steering rack...

    09 Yukon 6L80 TC shudder every 20k miles

    Update, the trans shop didn't seem like it was a big deal and they said they put a whole new transmission and torque converter in where last times they rebuilt my original one and put new torque converters in. He said for every 20 6l80 they work on, one wants to act like mine. Just won't get...

    Hey guys back at it. 09 Yukon LC9 5.3, 202k miles. Two problems today, for a while my coolant surge tank level has dropped an inch or two with every 500 miles or so. Haven't noticed any leaks but haven't worried about it because it was slow and I keep an eye on it. Day before yesterday I...

    09 Yukon 6L80 TC shudder every 20k miles

    The engine speed doesn't jump, or if it does its not noticeable. Just cruising listening to the radio, looking out at flat FL terrain and I see the CC light go off on the dash and feel the CC disengage. I never thought of why until it hadn't happened again until now. No biggy though. Driving...

    09 Yukon 6L80 TC shudder every 20k miles

    Oh one more question... before I had it replaced I noticed that sometimes when on the interstate in cruise, cruise would just turn off randomly sometimes. That happened again for the first time in a while couple days before the rumble strip effect. Would a TC slip cause cruise control to turn...

    Thanks for the detailed reply!! I sure wish I could do this myself. I definitely dont want to go in there and tell him what to do but this is helpful for me to know whats going on. So I do know they have (after the rebuild) replaced the TECHM when I brought it in for the hard downshifts...

    Nah they do the sheriffs and police dept tahoes. They know the 6L80. And the warranty is covering the 2 times I've been back in there. Not paying someone new when I have a warranty. Slipping would indicate pressure to me, no? And it was PERFECT since they had it last and 20-25 miles later...
