The summer after I bought the car I noticed a few second of delay when I put in drive. BUT, once it went into drive everything else worked perfectly. Shift points were normal no slipping during shifts...nothing, so I nursed it along for another year, long story short, it got much worse, but only the amount of time. And after that time, everything work normally

So anyway, I'm posting on here in hopes that I may get some useful tip, good advice and maybe even some useful historical knowledge.

This will be my first cast iron torqueflite that I've ever worked on. I'm been working on TF's for a lot of years but not the Cast Iron Baby.

So, assist away!

Than you so much

Internal leakage, most probably front clutch seal rings and/or bore issues and/or rubber seal

Like Sven said, leakage at the front clutch. As advised in the other thread, try an additive to rejuvenate the seals.

Take a look at this link that I had lost but have found. Chrysler Master Technician articles covering many of our cars in general and auto trans in particular

Yea, we stared with the additive. it didn't slow the leak or speed up the engagment into gear after pressing D. I'm wondering, should I be doing pressure test while the trans is still together to maybe help pinpoint the problem? Or many an airtest deal? I've never used either. I just tossed the spent frictions and put new in, buttoned it back up.

When I started this one I thought I was in the transmission section.

wizard, are you able to move a thread to a different section? If so, would you?

Thanks,

Wayne
