Re: Official 4t65e-HD Rebuild Yep the assembly goo or vasoline is only to temporarily hold parts and as soon as trans fluid warms up and moves through it then it will disolve. I use it on all bushings and moving parts so there is some lube on startup and trans fluid will work ok here also. Scotty the synthetic assembly lube I use is from a company named Life products, a similar company to and competitor of Lubeguard products. I get it through one of my parts suppliers and not too many places have it. |
