Transmission or gears

I do not like the way my psd changes gears. I am never hauling anything just cruising down the road and it seems like from 2nd gear through 3rd gear no matter how light I am on the pedal, it just does not want to change gears until it hits about 23 to 2500 rpm. What can I do to change that. I would like it to shift around 1900 rpm or so. Anything more than that just seems like a waste of fuel. Do I need to change my gear ratio or what??

With new gears it will still shift at the same RPM, but at a different vehicle speed.
You need a custom chip that changes the shift RPMs.

So all I need is a chip to fix that problem? Sounds good to me. Do you know of a top of the line chip I can use on my baby!

people here have great comments about DP-tuner and TS performance. i just bought a custom burnt TS perf. 6 position chip from Garrett @ BlackCloudDiesel. he put some custom two or three-off burns on my chip for the transmission shifting and torque converter. i also bought a lockup switch at the same time.

Thanks Strokin! I think I might go with the TS performance chip. What do you think about the Sonnax springs mod?? It seems like a cheap mod and it might help with my problem.

i love it. made it shift like it SHOULD have from the factory. well worth the $50. go ahead and get it, along with a relief valve/regulator.

Sonnex will make the shifts firmer, but the computer decides when the trans shifts. The Sonnex won't change that at all.

I think I am going to go ahead and order the sonnax! Cheap mods work for me. I am going to hold off on the chip until I get some gauges. Thanks for the input!
