Downshift problem

CofC_ZR2 · 08-12-2008, 02:41 AM

I installed the orange box Transgo kit in my 2002 4.3 S10. Now when I am driving in 4th it seems like the transmission downshifts to 3rd and then shifts back into 4th within a second. I haven't driven it much since the problem started occurring, but it doesn't seem to do it while I am accelerating, just during cruising and deceleration. Any ideas?

Also, I forgot to check for clearance after installing that Gold Shim from the kit in front of the 4th piston. Could that cause the 4th piston to not engage fully?

if you have 2 rings on the tip of the servo pin, the gold shim makes the band too tight.

so remove the shim and it should fix the problem?

i dunno, your explanation of the problem might differ from my experience alltogether. try it.

Would it be worth it to add a corvette servo and a sonnax billet super servo while I am in there? I have time to wait for the parts since I also have to install the lower intake manifold gasket on my truck.

um, lets get your trans problem figures out before we go adding more headaches. and a vette servo in an s truck that has NOT had the shell replaced with a hardened one is not a good idea.
