how much can i turn up my 12 valve
 

I have a bone stock rusty 96 cummins that i want to turn up alittle but i dont want to ruin my automatic transmission what would you guys suggest just turn the fuel up alittle

I'm having my share of problems with the standard tranny holding up (~300 HP),

I guess you should post a bit more info about how you use the truck, and someone with auto tranny experience can help... If you don't use your truck for towing, you can probably put a bit more power down, maybe just slide the stock fuel plate forward would wake it up a little bit without just ripping things to shreds.

I'll let an auto tranny person have the last say though

I drive the truck every day to work i dont tow alot but i do haul hay 2 5x5 round bales at a time and large loads of fire wood in the box frequently

I would *guess* that if you manually over-rode the upshift so it's not at full throttle during a shift would help the tranny cope with the added power... Also a good tranny oil cooler is essential even without power upgrades

My brother just traded his 95 dodge cummins with an auto. He ran it for a good while with someone upgrades without known problems. He slid the fuel plate all the way forward and noticed a good chunk of difference in throttle response, but it does hurt your mpg's a bit. He also took out the turbo silencer ring. There is no difference in power whatsoever, but you will notice a WAY better sound. I suggest you get a straight piped exhaust before doing any of this. Good luck to you!!!

Does broken off count as strait lol i have the four inch pipe waiting to go on her i just want alittle more power 185 hp isnt cutting it any idea how much power sliding that plate makes 250 hp would be plenty but i dont know if the overdrive auto trany can handle it

I think your ass-dyno would already be pleased with just sliding the plate forward... a 3K governor spring kit would do the rest, and that wouldn't jump the torque up too much for the tranny, just prevent it from starting to defuel at 2200

If you slide it all the way forward, I think it should give you around 70 horses. That should get you to your goal. I would suggest a better intake setup and an afe air filter. Although the plate helped, it felt like it had trouble catching enough air with the factory setup.

I've been talking it over with the auto guys around here...

Seems it's the low end grunt that blows up the trannys...

I'm not familiar enough with these automatic trannys but if that's true, just yank the plate and set your AFC full forward but crank the starwheel towards the cab for a slower spool up :rocking:
