First Gear in Automatic
A while back my grandfather was trying to pull out his 24 ft travel trailer from the side of his house. The truck and trailer were at an angle. Anyway, when he would give it gas in first gear (automatic), he couldn't get the trailer to move. He couldn't even get his wheels to spin. Is there a problem with his transmission? I had the same issue with my truck in a different situation. Is this just due to the TC not locking up in first?

Re:First Gear in Automatic
So its only an engine creating power issue? I would have thought that the torque on a stock CTD would be enough to spin the wheels. Guess I need to get the Edge....

Not neccessarily a power issue as much as a slushbox issue. It prolly wouldn't have done that with a manual. Manuals transmit more power and there's no fluid couplings to slip underload.

Re:First Gear in Automatic
I'm sure that wouldn't happen with a manual. I'm wondering if a transmission upgrade with ATS or DTT would resolve that. On several truck descriptions, specifically people who have had their a/t upgrades with DTT, they mention 89%, 90%, or 91%. Is this the percentage of lockup power?

Straight6: The number on the TC is a measure of fluid coupling. The higher the % the lower the stall speed. So for pulling a heavy trailer a lower number is preferrable. (More torque multiplication). <br>I'd check the tranny for slippage before blaming it on not enough power. My truck would spin its wheels on dry roads when taking off when still stock. <br>Ask about tire wear now. <br><br>Anyway, before doing any mods to the engine do two things: <br>First get some gauges- EGT, Boost, FP and Tranny temp<br>Second- check your tranny. The stock tranny will handle some light bomb like the EZ- if its in good condition. If it's sub par the bomb will just show this up. And if there is something wrong with it, get it corrected. A clutch that slips can cause a total tranny failure when not corrected in time.<br><br>HTH<br><br>AlpineRAM
