So this just started last time at the track. The tranny has fresh oil and was built for 600 Horsepower and have a shift kit installed with a B&M shifter.

So I launch and slam it into 2nd (No problems)
I hit 6200 rpms and I slam it into 3rd but it lags? like if i shift at 6.2k it wont shift til like 6.5k? like i have completely shifted and then it shifts.. hard to explain but I'm worried because its throwing my belt ever time due to the higher rpms then normal..

I havent had any other issues and isnt happening in anyother gears.. please help

Hi
is that a manual valve body? sounds like 2nd band is not released and drags while shifting into 3rd

[ChevySDime385]

Good question lol... I'm not sure. Any ways of checking that? like if its a manual valve body?

[Stranger]

Will the trans shift thru the gears automatically without you shifting it

[ChevySDime385]

Yeah if i leave it in "D" it'll shift thru all the gears and my Overdrive works aswell. When i get on it in "Drive" it "doesn't" go over 4500 rpms tho

Perhaps it's the TV cable adjustment.

X2 on cable, is it a fresh rebuild? may have to do with the way it was built or did it just start doing that ? need more info

Post #1 say's it all.

It just started happening. Well if it was the TV cable wouldn't it happen in every gear?

When I was putting the fresh motor in, the dip stick came out so i ended up replacing the oils, and the guy that built it was running a weird combo of fuilds. like 3 merc and 2 ford or something like that. Never had an issue until i replaced the oils and about 5 times down the track it started acting up.

you may be slipping in 3rd, that blend of oil may have something to do with it The F type will give more of a grab Id talk to the guys that built it for you they will have a better idea of whats going on
