I used to have a lockup TC in my 700R4, I recently needed it rebuilt & when it was placed back into vehicle they used a non-lockup converter. Now it seems to run hot, especially at higher speeds & on an incline. Can I install a universal lockup kit (the kind that comes with an oil pressure switch & is hooked up to the side of the transmission housing?) Or do I also need a "lockup" TC?
Here is the kit I want to install: https://www.amazon.com/Superior-K013-High-Gear-Package/dp/B00BZODL5G/ref=sr_1_4?crid=MI2I0TSQI0NO&dchild=1&keywords=700r4+lockup+kit&qid=1592331827&sprefix=700r4+lock+up+kit%2Caps%2C879&sr=8-4
