Hey yall,
I recently turned my truck into my daily driver and today on the way home I noticed that my trans. wasn't wanting to go into third. Any Idea whats going on?it shifts into 2nd fine and then when it reaches time to go to 3rd it stays in 2nd and if I let of the gas it will shift.

vacuum troubles maybe?

GREASEMONKEY72 · 06-05-2007, 09:36 PM

i dont think its vaccum but it could be, check the vac line from the intake to the trans, but i think it might be in the valve body of the trans or even the TQ converter but i could be wrong

Did you check the fluid level?

duh to me

Yes, That was the 1st thing I checked. Then I checked the vac. line everything looks good. Fluid level is good and vac lines are good and tight with no cracks. could a piece of trash some how or another got to the vac line and blocked it?

GREASEMONKEY72 · 06-05-2007, 09:59 PM

its possible something could be clogged

dont take this the wrong way or anything but you did check the fuild with it idleing in park right?

but if fluids good and the vac lines are all good then i think its either the valve body or torque converter

It wasn't taken the wrong way,Alot people dont know to check the fluid with the engine running and in park. But to answer the question, yes I did.

I agree--they are about 10 bucks

It died. I drove to work today and as I left the house this morning it shifted fine through 1,2,&3. After it warmed up it wouldnt shift into 3rd and when I did get it to go into 3 it would slip like crazy.So, out with the old and in with the new. I will be picking up a 700r4 tomorrow afternoon and dropping off my drive shaft to have it reworked. Which brings up the Question. How long does my driveshaft need to be,or how much needs to be cut off of it??

To be accurate with the measurement, the trans should be installed THEN measure it
