Ugh, Cant Take It Anymore!
 

alright, i have a th350c tranny and the damn lockup converter kicks in at like 26mph, then if i give it any gas it will downshift again....long story short, its a big pain in the ass.

so how do i disconnect the damn thing? isnt there a wire or something??

also, i was thinkin about maybe wiring up a toggle switch to make it work, so it would be in third with the switch off and 4th with it on. would that work?? how would i go about doing it??

Correct me if I'm wrong (I ocassionally am) but TH350 don't have overdrive and therefore don't have a lock up.

You are correct that a TH350 does not have a OD but the later models came with a lock up converter. These are TH350C models.

79BIG10 is correct. There was a lock up converter TH350.

My old th350 had an electronic lockup

Mine just started doing that a couple of weeks ago, I thought the tranny was going....
Is there a fix to this problem?

well ive heard before that there is a spring in there that activates it, and if you are getting your tranny rebuilt then you can get a stiffer spring to put in there so that it shifts at a higher point than the old worn out spring...this is not an option for me YET though becuase i dont plan on rebuilding my tranny till i get a new motor and that is gonna be a while.

ive also heard that oyu can disconnect the lockup altogether just by cutting one wire, i dont know if that is true though...but my idea was that if there was a wire that controlled it then i could put a switch to it to turn it off and on. i would do this becuase i like being 1:1 when cruising on the highway, but i hate when it comes on and off all the frickin time in town.

and btw, a th350 doesnt have a lockup converter, but a th350c does.

I wouldn't unplug it unless you want to rebuild it pretty soon. I thought I could get away with doing that and it burnt mine up in no time at all lasted maybe a month. This was because the connector that goes into the transmission was broken and I thought I didn't need it "that" bad so I didn't plug it in. I was already broken so there wasn't any sense in plugging it in. That's just been my personal experience with it. TH-350 are also a little stronger than a TH-350(C).

A buddy of mine put a switch in his so he could lock the converter when he wanted to and leave it unlock normally.

Can you tell us how he did it? I dont want to put a tranny in it now, I am savin for a 700 r4.
