wen i hit my gas pedal off the start it revs up but dosent go to fast then it feels like a powerband and it kicks in and it goes good, im am lost i dont no what it could be,

 

sounds like weak trans pressure. slipping first gear. check your fluid and see if it's full, does it smell burnt?

 

fluid is full almost to the top, and it dosent smell burnt, but it looks a little brown..does that mean my trans is going on me?

 

kinda confused here....

is this something new? or do you feel like your car doesnt have power relative to another?

CEL on?

 

it feels like a lack of power on the bottom end. but i have a small crack in the manifold that just recently happened so could it possibly be that?

 

oops

 

an exhaust leak will KILL your bottom end, but if its not a big crack it isnt doing much.

 

X2 on exhaust leak, robbing bottom end power. No computer codes? Are there any recent changes, tires, lift ect. What gears are you running?

BY the way.. Where did you get a D35c front axle, I've not ever seen one.

 

Thats cause they dont make them...

 

well i thought most xj's come with a dana 35 n the rear and a dana 30 in the front..i got tht from rustys FAQ's

 

well it has 33's and a RE 5.5in lift but i put that on a while ago, i just noticed the crack in the manifold so i think thats the prob..and no there arent any codes

 

Depends on Year, ABS, Package, ETC

Your best bet would be to post a pic of the rear axle (please dont start a new thread), the D35 has a rounded housing, the 8.25 has a flat "lip" along the bottom.

I REALLY hope you dont have the 35 in there, with 33" tires. Youll be snapping axles like crazy if its locked.

D30 is the standard for front axle

 

my truck used to do the same thing it was like the tranny didnt want to shift it would just rev the **** out of it till like 4500 rpm and then it would kick down and go. it was the throttle possitioning sencer i changed it and it was fine

 

well i have a dana 35, its not locked but i dont plan on locking it
