My truck seems like it reall makes no power in 1st gear, 2nd is a tad better but it really dont pull till it gets the convertor locked up. Does that mean the convertor is gone south? Truck sounds like its going 800 mph but really does not pull very hard. you guys have ideas on what to check? change? adjust? The truck has 61k on it and last transmission service was at 52k. I dont know what version of the auto I have, but any help would be great.

Thanks

 

Naa. That is just the nature of the beast. Floor it, and the engine revs to about 2300 and just waits for the truck to catch up.

You should probably increase the line pressure a bit. INstructions on dieseltrans.com

 

i looked on the site, from what i saw, it only showed what the pressure specs should be, and not how to set it. Im no tranny guru
