67' Transmission Fluid & Slippage

["jsadowski" <jsadowski@xxxxxxx>]

You should be using Dexron or Dexron/Mercon. I would try changing it if you suspect that wasn't what was used. If the trans was a lot of miles on it & the fluid never changed, changing it could cause problems to start, even with the correct fluid. My daily driver  Fxxd had 190,000 miles & I wanted to have the trans serviced. The service manager told me not to even think about it. Doing  so could  potentially kill it on the spot was what I was told. My sister once owned a 67 polara & a mechanic friend told her pretty much the same thing.

Subject: IML: 67' Transmission Fluid & Slippage

I just have a quick question(s).... What is the recommended transmission fluid for my 67'? (I only found notes on a '58 in the archives).

 

Recently I had my transmission filter changed, and now I have noticed some slight slippage under harder acceleration? I am assuming it's the fluid, as I never had slip before...?

 

Thanks,
