anyone else seeing intake mods causing drive abiliy issues... low speed under 35kph on the 1-2 up shift car is clunking into 2'd, down shift from 2-1 is horrid, cabfeels like it want's to jerk and come at a stop go car has 4k on it thoughts'? not noticeable at speeds above 40mph. calibration from dealer?

 

Never noticed anything like that. Did you just install something? If it's an intake, I'd double/triple check for leaks.

 

Had my injen for a while and never had any issue too....

 

Mine is stock and the 1-2 and 2-1 shift is harsh, I just turned 4k miles, has been that way since about 900 miles. I seen a post for a calibration tsb that is to help correct this. I have not had an opertunity to take it to the dealer yet. My shift button is also sticks, prob not related but, it clunks now and then when I go to put in rev some mornings.

 

I think there might be a transmission TCM update...... check with your dealer. I had 1-2 and 2-3 shift shock and I had my control module updated a few months ago and it reduced it a lot.

 

Check all the connections just to be safe, i had a crimped vaccum hoses and noticed some power loss (i know its not your problem) but just just in case
