Truck shifts fine with out slipping or slaming into gear but wont shift to go faster then 45 mph i think its my overdrive when i had the transmisson rebuilt they cut the wire to the overdrive when it was off.... any ideas on how i can fix it myself?

 

splice the wires together?

 

i have no idea what wire is the one for overdrive

 

first off you need to find out why the truck will not go over 45 mph, unless you have very low gear rear end you should be able to get a least to 60 mph without overdrive granted it will be screaming. According to the FSM, the two wires you are looking for will be on the driver side and should be part of the wiring going to be speed sensor and neutral safety start sensor. The color code for the overdrive will be read/LG which I believe is green tracer the other wire is dark brown if I'm reading the FSM correctly. You really need to fill out your signature so we know what truck you're talking about. Just my two cents, Mike.

 

Mines does the same thing But I can go faster than 45 miles an hour it just isnt in overdrive

 

She will go faster than 45 i just dont want to be pushing 3500 rpms :P lol

 

You should be able to go at least 60 mph and stay under 2800 rpm or at least not over 2800 rpm. It sounds like you're going into third gear. Just my two cents, Mike.

 

she sits just under 2900 when she is going 60 my overdirve just wont turn on. any ideas?
