Ive got a 91 v6 auto surf, im selling it.
The overdrive isnt kicking in, only sometimes after a decent run when it really warms up.
Now what seems to be the most common culprit? have heard the overdrive temp sender, or vacuum hoses going from trans to the modulator?
Who in Auckland may be able to fix this? Ideally want someone whos done it before, so they can just get in and fix it.
Im selling it for bloody cheap, thought though if i can fix this for not much coin or beer
