TH350 3rd gear question

[Rice Killer]

When shifting into 3rd @ full throttle it just slides into gear, and the other day I tried the 150 shot and it really didn't like going into 3rd. What can I do to this trans so that it grabs 3rd just as good as the 1st to 2nd gear shift without doing a complete rebuild. ie manual valve body?

specs
th350
aftermarket heavy duty clutches
4000 converter
shift kit

thanks

I have the same thing. I but in a transgo shift kit and it did not grab as well as my b&m but it did not grab 3 like 2. I think the only thig that would do it would be a manual valve body (not fun on street). I hope someone else has an idea.

If you haven't burned the clutches already, B&M transpacks work well. Doesn't sound good though...
