so i did the tb mod and i switched all the plug ins except the one the goes into the tb looks like a mushroom my issues is now i get slow shifts when i go slow i have to hit about 2500rpm before the car shifts into second all the gears are delayed in shiftin but real strong when they shift and now when im going sixty or so and step on the peddal the car is a beast and moves but when i hit like 4200 the car drops down a gear well feels like it and hits like 5500rpm did i mess up the linkedge or what can the issue be?

thanks

 

What exact "mod" to the TB did you do and what plugins did you switch?

 

getting rid of the side walls on the top of the tb and the rectangular one that has the lil hose plug in and the one that turns the flaps in the tb only one that stayed from the bought tb was the one that looks like a sensor?

 

Maybe you should post what yr/mk/mo/eng you have also because it doesnt seem you have a HEMI

 

sorry that would help

2002 ram 1500 5.9

 

See, I know very little about the 5.9 but HammerZ71 or someone else might can help.

Posting pics can always help also

 

i switched the old sensor and the car wouldnt start would just stall i would have to rev it so i put in the newer sensor and same thing so i reved it while in neutral and it sputtered but ran took it around the block felt like longer shifts were happening

would one of the throttle cables or something get more play in it then before thats why it stalled with out reving?

 

drove the car today start up with no issues still long shifts i reseted the pcm so idk what it could be, im hoping its not the tranny? should i get a new IAC sensor? would that help the shifting
