My 01 Screw has a shutter bad from off of the line until 10mph. It is lifted 4 inches and the pinion angle looks off so I bought shims to correct this but is there anything else I should check when Im under there for this issue?

Thanks Dave!

 

Ok so I checked the pinion angle and it looks good. Anyone know what it should be or what else the problem could be? Thanks Dave

 

ltd slip rear end? If so ....worn out clutch packs?

 

Ya they are worn out but it is when im going straight not turning and it feels like a u joint but they are tight?

 

4r70w auto tranny
torque converter shutter

 

Its only in first gear under 15 mph...ya think?

 

sounds like it..do a search see if it sounds like the problem your having.

My definition: shaking during low rpm's, the car/truck will not accelerate very fast then all the sudden its gone. You will notice it more going from a dead stop.

have you checked the tranny fluid see if its low? Torque converter shutter has something to do with the vaines in the converter not giving the transmission enough fluid.

I think there is an additive you can buy to help fix it. Dr shutter/ mr shutter something like that.

 

Dr Tranny Shudder fix IIRC.
