"Bump" When Trans Engages

[TMAG6.0]

I feel a bump when going from reverse to drive and when taking off from a red light. Its most pronounced when I get off the power then get back on it. As if you were approaching a red light to stop but it turns green. Big bump when getting back on power.

It doesn't seem to matter if trans is hot or cold. When cold there is a longer lag between reverse to drive.

Any Ideas? New Trans time? I pull a 8,000lb trailer often

Ford says some of that is normal. With that many miles and towing it’s time to check U-joints and the carrier bearing

Had same prolbem with mine. Thought it was the tranny going out had it rebuilt and had the same prolbem we replaced the direct drive silinoid the one that controls first and reverse and that fixed the prolbem. Only a 70$ part and 30 min labor. That took the lag out of going from rev to drive and park to drive.

Is that solenoid something I can do myself? Is it a big job or plug an play?

Ill try the solinoid thing, im sure thats it but it could use a new one anyways. how do you check the u-joints and such? Im not much of a tech, just self learned. I will at least try. thanks

It's not hard you'll have to drop to pan, remove ( lower) the valve body and wire harness ( that's so you can pull the solenoid out it just plugs in) you'll need to know which one it is though. I'll have to vet my tranny manual out in order to tell you which one for sureand I'll post some pics with it also. If you need the info asap let me know I've been working 12 hrs 6 days a week sometimes more and hard to get to shop so let me know
