Yesterday I was going up a long hill and needed to pass a vehicle. I pulled it down into 2nd gear, expecting additional passing power. Instead, the truck actually slowed down. I had to go back in Drive to regain my speed.

Is this sound like a bad 2nd gear clutch.?

Works fine in drive.

97 12 valve, Everything standard, no modifications at all.

Appreciate any advise.

 

how fast were you initially going.

 

bout 55. It runs real good with overdrive either in or out. But in 2nd, it seemed to have more power but actually slowed down.

 

not a auto guy at all, but just curious what are your rpms like in 2nd at 55?

 

didn't think to look. It had been so long since I needed to use 2nd gear.

 

i was just thinking your over reving in 2nd at 55.

 

My guess is that it was defueling.

Pardon, but what is defueling?

 

hes refering to the point where your truck runs out of rpm gain. usually limited by your fuel plate and or governor. stock governor takes you somewhere around 2300rpm depending on your pump. which is why i asked earlier what your rpms were at 55 in 2nd. if your over 2000 you wont be gaining R's. unless you upgraded your gov. springs.

 

Thanks for the info. What part of Texas you from?

 

also at 55, i'd think ur TC would be locked up, and when u downshifted it unlocks and u loose the 1:1 power ratio, and that mixed with the defueling would equal slowing down. Install a "3gsk" and u won't have the defuling problem, u'll be able to rev around 3200-3400 still fueling.

But also, ur trans sounds like a candidate for a upgraded Torque converter and valve body, it would really change ur truck.

 

in third u should of had plenty of power before i had gsk 55 was topped out in second at about 2600 and sine i got governor springs i can run 65 in second
