but i wouldnt recommend it on a stock transmission.

 

i just did my tranny about 3 months and put billet input shaft t/c strait cut overdrive planetteries in and messed with the valve body to get rid of some shift over lap do u think that will handle it and why do you say not to do this on a stock tranny my 97 is stock and i would like to put this switch on it

 

You can put it on your stock trans. I have had one on mine for about 8 years and it is the original trans. 230000 miles. It is now showing signs of needing rebuilt. I believe it is mostly the converter. I do not attribute the need of repair to use of the lock up switch. I would say it has prolonged the life of the trans. It all depends on how you use it. You should not shift the trans., under load, with the switch locked. I could see where you could do some real damage under full pedal. When I take off I turn my OD off and lock the converter when it shifts ,on it's own, to D. I get to the speed I want in D, then I will leave it locked up and flip the OD switch to let it go into OD while locked with the switch. I just let off the pedal almost completely during the shift. Once it shifts I roll back on the pedal and it is as smooth a shift as you could want. Once you get the timing down with that you lose almost no momentum. I have hated the way this truck shifts from the day I bought it 10 years ago. Thanks to the people on here I have learned to make it shift the way I want it to. The lock up switch has also saved my brakes as I can leave it locked in D while going downhill and not have to use my brakes near as much as with the converter unlocked. Without the switch the truck pretty much freewheels downhill and I was on the brakes all the way to the bottom.
If you use it right the switch is an asset to any truck with an auto trans.

 

Ill agree with what starflite 3 said it really depends on how you drive it i'm just a little hard on things and used the lock up switch while shifting through the gears full throttle

 

With a '96 you may have to have the dealer flash the computer for a lockup to work.
Earlier '96s had some of the programing for the older RH transmissions, causes the lockup switch to not work right.
'96 have a RE tranny. Flash costs about $80.

 

I think I remember reading some have wired the switch with a relay through the brake switch, thus, stepping on the brake will unlock the TC. Can anyone confirm this? I don't have the lock-up switch but have been thinking about putting one on.

I believe I read about this as well, using the brake pedal to unlock the converter switch. I didn't do it because I thought I would still use the brake going downhill and everytime I did it would unlock the converter. I like the switch better. It stays locked going downhill no matter how many times I step on the brakes.

 

I read that someone had used a hobbs switch in one of the test ports of the transmission, with a set of relays, that would kick out the lockup if you forgot to manually unlock it.

I haven't found a full description on it. Any one know where it is?


This is the closest I have found, but not the hobbs switch one. I figured I could possibly work the switch in, but a already diy thread would save me some time.....

 

Good point, sometimes I don't think it all the way through.
