change the tranny on my da teggy and now the temp gauge doesnt work. while the check engine light also comes on sometimes. any help?

 

you maybe didnt hook up the temp gauge? lol.. some sort of wiring issue is afoot..

start checking ALL of your connections on your sensors, and the wiring, and ALL of your grounds, fuses, relays, etc...

go back through what you took apart in your mind, and look at it, and you may find the issue

I would say your gauge isnt working because of a bad connection to the temp sensor, which is a brittle, 1-wire sensor, under the dizzy (if im not mistaken.. correct me if im wrong)

 

I think its broken is it the one connected to the block? right under the dizzy?
