Transmission question

Posted by humanpotatohybrid On 2022/10/29 11:20:21

On my 55 400, whenever I put the transmission into gear the first time after starting, it stalls the engine out unless I rev the engine pretty high. Doesn't matter whether I put in in either Drive, or Reverse. However once the car is going, it works just fine. I can stop it and change gears at idle perfectly normally, even after only a few seconds of driving. Likewise I can put it back in Park/Neutral and not encounter the same problem.

I've tried to let the engine warm up for a few minutes first, but that didn't seem to make a difference. I've looked in the troubleshooting section of the service manual but there's not anything I see that matches this problem.

I'm using type FA transmission fluid (that was the bottles of fluid that were with the car when I bought it, and I topped it off a while ago using an unopened one, measuring the level with the procedure in the service manual).

Anyone have a guess what is going on?
