A buddy of mine has issues with his 99 Sierra with starting under cold conditions. If it's plugged in starts no problem. If it's summer no problem. If it's in a garage no problem. But if the temperature even drops a few degrees below 0* Celsius (Canada) which is really not cold at all it won't start. Turns over but won't start. Battery, spark plugs, plug wires, alternator all like new. Any ideas. Confused!

  Mine runs 145 to 158 ,95% of the time. ‘25 1500 with 5.3 and nht option. Wonder how long it will last? Wonder how much water is in the oil? Bought it in Oct 2024. This was today in south Louisiana.

  The exchanger is bolted right to the driver's side of the transmission. Would I go as far as to call it a heater? No. Does it aid in warming up the ATF to reduce friction as quickly as possible? Yes. What's the internals to it? No idea. Never cut one open. However, it's primary role is maintaining transmission temperatures once up to temp. No different than an oil to water exchanger for an engine oil cooler setup like GM uses on say 2010-2024 Camaro with V8, or 6.6 Duramax. Gas 10L80s (so 1500 truck with gas V8) have a thermostat in the valve body but not the cooler lines. 2019-current. 3.0 Duramax with 10L80 don't have a thermostat in the valve body. They have one in the lines going to the auxiliary cooler. 2020-current.
