I had some horrid tranny problems before, it didnt have enough pressure to completly ****, but i changed the fluid and the filter and the vacuum module. it seems to work better, but i don‘t think its gaining all the pressure it should. i heard in several cases that add additives like that lucas tranny stuff helps the pressure and shifting. pros and cons of using it? ive already built this tranny 3 times, i just want it to work, and i want to sell it.
Lucas is about $10.00, what have you got to lose? I have heard good things about it but wouldn't swear by it. Good Luck
The additive or brake fluid, either one softens the seals-Just make sure the other end at the engine doesn't have a cracked or loose vacuum hose.If the engine is missing {running bad} you won't have enough vacuum for the modulator.MAKE sure you have the same [volume] of vacuum the engine end as U do the Modulator.
Lucas is the best I'v used it and it does what it says.
