TH350 help

Before I put the rope round my neck is there anyone who can help me !
Question: Can anyone confirm the length of the detent valve control wire in a TH350 please ? (the one I have is straight with a cranking handle shape at each end and just over 5" long)
Thanks.

wow great pictures many thanks. What I'm trying to confirm is the length of the wire because mine hits the tapered end of the sleave before it actuates the kickdown.

The only way my car is working at the moment is with a slightly shorter length of galvanised wire in place of the original as shown in your pics. What remains a mystery to me is how can the original wire grow in lenght or how can the sleave shrink ??!

howdy there,

hmm interesting..

did you swap the cable from another application ? maybe you just have the wrong application/length cable

such as 2bbl one on a 4bbl carb, etc

brackets and distances differed often at the carb end of the cables.

sounds like you need more cable length with the same sleeve length you have

hmmm

good luck

it is common for the little bracket the wire attaches to... on the trans valve body to bend.

that would alllow the wire to travel out of the trans case further.

BRILLIANT thats it ! It has to be the only expalnation because I have tried both the standard GM cable and a Gennie aftermarket cable and niether work. So off with the sump again and check the wishbone bracket. Why didnt I think of that, wood for the trees an all that !!? Thank you so much Mr Crosley Sir.
BTW what do you drive ?
Oh and one more thing please since you seem to be so knowlegable. When I'm on the strip manualy shifting at around 5000 rpm, should I lift the throttle slightly or keep it loud. If I do the latter it tends to slip as it shifts up and obviously that effects my ET. Sorry not sure how to make pic large.
