In my 98 dodge cummins it has a rebuilt automatic transmission about 6k miles ago. It seems to me like it shifts slow as heck. It takes me about 27sec to get from 0-60mph on a flat highway. My question is that does that sound about right or is something wrong? It ussally shifts pretty good tell about 0-40, but that 40 to 60 is very slow.

 

that does not sound right at all to me. hope ya figure it out

 

I had the exact same problem. I did the the basic stuff, moved the fuel plate forward all the way, the AFC housing forward all the way, played with the starwheel a bit, capped the wastegate hose and cut out the muffler and put in a straight section. now my truck is an animal.


next come the 4000 rpm governor springs and 60lb exhaust valve springs, a new fuel plate, torque converter, and valve body. then 5" turbo back exhaust. then... and then..... and then....


this is my wife.

 

27 seconds?!?!?!

 

How long does it take you guys to get from 0-60?

 

even on a bone stock truck you should do 0-60 faster than 27 sec

 

Would changing the fuel filter help at all you think?

 

when was it last changed?

 

fuel filters r like 25 bux max at oreillys... id start there

 

Last i remember its been 30k since the last fuel filter change, but i'll pry start by changing the fuel filter and then go from there
