Title: motor rocks and jumps when put into gear
Post by: Crazymays77 on August 22, 2011, 05:30:56 PM
ok so i get the tracker all done and it runs awesome. But the motor rocks pretty bad and when i put it into gear from park or neutral it jumps. I really dont like it doing that. So what are my options to fix it from rocking so much and jumping when i put it into gear?

idle could be set to highwith it jumping from neutral or park which is a non moving gear to drive or reverse

Idle is 1000 in gear it's about 800. Don't want to go much lower than that on idle if I don't have too. Figure a stall converter around 1500-1700 would be a good idea. Problem is there r two different spline counts for the 700r4 and I don't know what mine is and I don't want to pull it apart just to figure it out and put it back so I can play till I get the stall.

That's the other thing I don't think the tracker can handle the solid motor mounts. Might have to idle it down and see what happens. Also I need to fix the front shaft ujoints. That could be some if the jumping.

normal idle on a 4.3 is 650-800 rpm id say stock stall is probably 1000-1200

It wants to move on it's own at idle. I'm gonna lower the idle and adj. The timing on it too maybe that will fix it.

As soon as I put it in gear it wants to take off.

Really don't want to spend 200 bucks on a stall.

All mounts r brand new from quality auto. Maybe but usually font get bad parts from them.
