If that 727 was in use with no filter that’s really bad and it’s time is limited. How long was it run like that? Too long I can tell you.
What year, engine, and car is this in?
Seal conditioners only work on lightening your wallet. They don’t fix anything. You can usually take apart the trans and find the worn seals or seal surfaces that a conditioner would have zero effect on.
I agree true part throttle kickdown is on 1971 and up.
It’s a 68 Sport Fury with a reman 383. I have put about 10k miles on it so far. I drive to work and back about 24 miles a day. Transmission has been good up to this point. It has had several fluid changes so far.
I have NO kickdown. Not even at WOT. The fact the filter was missing when I bought it (2018) makes me wonder if someone screwed around with the valve body, or lost parts.
Prior to my buying it, it sat in an impound lot for a while. It was sold to the guy I got it from who wanted the motor for a B body. Fortunately for me, the motor was shot and the guy had to sell it.
I manually shift to 2 when I get on the interstate. Going back to D, it takes a second or two to hit 3rd. The harder I push it the longer it takes. Other than morning slip it seems ok.
I did go through all gears and have let it sit in neutral for a couple of minutes before I drive it. That seems to help for now.
Likely I will have transmission guy do it. He says he can change rooster comb so I have reverse lights off of 69+ NSS. I will probably pick up the better valve body and have it put in. I just don’t have time to learn and rebuild it myself. List of honey do’s and my upper control arm bushings need immediate replacement. They are worn and I am eating the inside of the passenger tire.
