Trans slippage question
TRANSMISION QUESTION
Hi all I need some advice, I am running 2005 PSD, with about 29,000 miles, on the clock. I have been noticing some hesitating or slippage when it shifts between 2<SUP>nd</SUP> and 3<SUP>rd</SUP>. it doesn’t happen all the time and it doesn’t seem to make any difference how much foot I but into it. I thought I read some time ago that this is common with the ford trans. has anyone experienced this, and will a tuner solve this problem

It sounds like what you are describing is known as "shift flare". A brief spike in rpm's when up-shifting, most common with shifts 2-3 or 3-4. I have a slight flare between 3-4 which has been there since new with no change in 45k miles. Some FTE members have reported firmer shifts with certain programers/tuners.

My 06 did the same thing. I drove me nuts. Every time it did it I would cringe thinking that my transmission was on its way out. A phone call to Spartan Diesel Technology for an SCT X3 took care of it and I picked up 1.5 MPG to boot. My truck shifts awesome now. THANKS Matt.
