Iinstalled my stall converter today and now the car wont upshift while in drive HELP PLEASE!!!!!!!

 

Did you hook the linkage back up? With the car safely supported, have someone move the shifter back n forth through the gears and see if the linkage arm on the trans moves. There is disconnect on the cable that is easily broken and will let you pull it back to R, and then D, but going back nope.
If you mean you put it in gear and you roll in 1st, but then no shifting to second...beats me.

 

It let me go in D and R or N but it wont up shift while in drive i checked the harness it fine put a new shift noid& harness and my speedo dont work!!

 

out put speed sensor in the tailhousing (the car doesn't up shift because it thinks it isn't moving if it has no speedo)

 

Ah yes, the VSS connection. Plug it back in as back4more said and you should be good. Its the pass side read of the tailshaft. small 2 wire connector.

 

I will go try it now THANKS alot guys

 

well that did not work my speedo still dont work but its pluged in

 

Did you check ALL the fuses? they pop on occasion with a trans in and out.
Also i know u said u checked the case connector but there maybe a bent or broken pin. plus,if you push too hard on the case conn. it starts to go into the trans and sometimes doesn't make a good conn.

 

well i replaced the connector with shift noid.Do the speed sensors go bad?
