    Transmission cooler inside radiator

    Question? Finally got time to pick up a transmission cooler nice larger 11 x 12" unit. My question is - is it better to just bypass the whole in radiator cooler or to use this inline with it. I have the Yukon Hybrid and I have read on here that the coolant will help bring down the trans temp but...

    Hybrid Transmission - how to check fluid level

    Does anyone know how to check the transmission fluid on the 2013 GMC Yukon Denali HYBRID? The manual does not tell you: when running or off? in Park or Neutral? They have unique transmissions, in that they have an extra pump to run when the engine is off. When I check mine and the engine is...

    Transmission cooler inside radiator

    Do you have a cooler or deep pan on yours? What brand ATF fluid are folks running? And has anyone used a friction modifier with success of lowering the temperature or are the synthetic ATF good enough?

    Transmission cooler inside radiator

    what is the temp yours runs at on the highway not towing with your cooler? Just driving 70 mph or so. Mine seems to stay in the 165-175 range 60-75 degrees outside temp fairly flat terrain Fort Worth to Austin, TX.

    105K Spark Plugs compared to New

    my understanding is that there are 2 water pumps one that runs on the engine and an electric one for during autostop. That is why there is an extra coolant reservoir under the hood. My autstop has worked with the temp as low as about 170

    105K Spark Plugs compared to New

    I will have to give it a more critical look and see if it goes a tad past. Could I get that code read at an auto parts store with their reader. I do not have one?

Just changed the fluid at 100k good pink/red color. I found out that the Hybrid does not have a torque convertor it has a different system. Mine has a...

    105K Spark Plugs compared to New

    I have had it since November and it has never gone over the midway 210 on the gauge. I wonder if the Hybrid starting more often due to the auto shutoff in traffic could cause that.

    105K Spark Plugs compared to New

    -- The part # out and in are AC Delco 41-110 Professional Iridium Spark Plug. Got them for a steal from Amazon Prime free 2 days ship back in January. $25 for a set of 8 plugs. I thought that was great but I always check for Manufacturers Rebates. AC Delco had a $3 per plug rebate going on so...

    105K Spark Plugs compared to New

    I thought I would post these spark plug picks for fun. I bought a used 2013 GMC Yukon Denali Hybrid 6.0 with meticulous service records showing no plug change in the low 90K miles. The suggested spark plug change is 100K. I got around to it at 105K. This is what 105K vs New AC Delco Iridium...
