I left my truck plugged it last night, came out this morning started it up no problem came out 10 minutes later got in my coolant temp was at 140* and fuel pressure was at 19 psi everything was normal. Then I pulled the gear selector into drive it kind of jumped and then died. I turned the truck back on immediately after it died and it drove fine. Any ideas?

Do you have an aftermarket torque covertor?

 

[98C]

Yes fully built sun coast transmission with a triple disk.

Did it again this morning under the same conditions. Help?

I am guessing your auto is not liking the COLD and not acting very nice with a stiff torq converter.
Is there a lock up that has not unlocked?

If the heat exchanger has been deleted (Pass side beside oil pan), you are not getting the coolant heat transferred to the trans. I will guess that you have larger injectors & a lower stall convertor.
Please fill out your sig, so that we can help you better.

start it and immediately shift to neutral, this will flow the fluid and warm the trans with the engine.

try this and see what happens.

My truck does the same thing in the cold, try what off road said it may help. The stalling is caused by the low stall on the aftermarket TC and if you have aftermarket injectors that makes it even more common. when I first put my truck in gear after it's been sitting for hours I bring the rpms to about 1000 and that prevents the truck from stalling

All Suncoast & transmissions that have modded valve bodies (To my knowledge) have the full flow oiling mod to flow fluid in Park.

ed, i have seen and driven transmissions that say they do that, and it seems that some do some dont.... not saying they are liars, but i have had much better luck and less breakage with just shifting to neutral.....

 

[Yankneck696]

Every shift kit has the mod to do it. THe top trans manufacturers do it. It also provides for better cooling. He is letting it idle for 10 minutes. I suspect that the heat exchanger has been bypassed.

I don't think its been bypassed but the trans temp is at 30* in the pan when I try to shift it in to drive. Yes I have 7.010s

 

[98C]

Would I be able to get like a block heater of some sort and put it on the pan to help this?

 

[Off-road]

there are magnetic block heaters.....

 

[Yankneck696]

If it is warming up for 10 minutes & you have a Suncoast, the exchanger is most likely bypassed. Your trans should be within 30-40* of the engine temp.

Ive never seen it get within that one time. The highest ive seen it is 165* towing 10k...
