The stock auto will hold ok with a #6 plate, boost elbow and 3GSK, as long as you don't drive it too crazy. You only need to turn the pressure up 10-15psi.

I did that to mine at 75,000 and it's still isn't fried at 215,000, and that's even with towing up to 14,000lbs. The main thing is controlling the TC lock-up timing with a switch. If you don't let it lock up too soon, you can make things last a long time.

Even with my latest rounds of mods (400-450hp), the trans is still working, just can't get much of the new power to the ground. But that's going to change here in a couple of weeks when the Billet Goerends gets here

Word up on the trans. upgrade plus you'll appreciate the engine mods that much more. I've had pretty good luck with my auto also and have beat on it but she's getting pretty soft.

Atleast do a TC and VB before adding different plate, 370s and AFC. Then later when the cash is comming get a tranny and put the TC and VB in if still in good shape. Also 370s run hot so might look into intake and exhaust before anything.

with all this being said about trannys lasting with a vb and tc. would it be a good idea to get a tc and vb from the same people you would be looking to get a tranny from? I have a tc and vb but i have no clue what kind they are so that might affect what tranny i get.

Oh the actual DODGE transmission itself is TOUGH.. industrial tough. BUT, the vb and tc are the only real weakspots.
