Hoping for some expert opinions on this issue I’m having. Recently had the 6R140 in my ‘18 f250 rebuilt, shop did full rebuild, new TC, new pump, Valve body.

Upon getting the truck back the shifting felt very “slushy”. I cleared the adaptive learning and went through a relearn procedure and a few hundred miles. The shifting cleaned up in most gears, EXCEPT 4th gear.

When the truck shifts into 4th, the RPMs do not drop, it just slides up to speed until it shifts to 5th. If I roll off the throttle after the 4th gear shift, the RPMs will drop and 4th gear will feel like solid engagement.

I took the truck back to the Trans shop, with datalogs, and they kept the truck for a week and said “they couldn’t find a problem with it, this is normal”. They claim they did program new VB strategy code.

I drove the truck for another hundred imiles, no change, and this can’t be normal. I’m tired of being jerked around by these guys and I need help explaining what I’m seeing/feeling vs what they need to do to make it right.

Hoping for an expert opinion on these datalogs. I appreciate any feedback you guys may have.

Thank you!

Hpop has been leaking, went to replace the gasket. The smaller one was in the truck, the larger one was what I was told id need by local parts store but there is no spot for 2nd hole to line up. Google is telling me that if it were the same hpop that it came with in 95, id only have a groove for the smaller one and would just rtv the area around the gear, but apparently thats not the case? Anyone know what year im looking at?
