It seems like I have to give it more throttle when taking off from a stop to get the truck moving. Is this normal or is it just me? What whould happen if the VB did not make a good seal when tighting it? Sometimes I get a hard shift to 2nd other times it's not as hard. Just wondering if the VB did not seal right when I bolted it down? If it didn't seal whould the truck even move?

 

Give it some time to fill up with fluid and the computer to adjust..Mine took almost 600 miles to properly...

 

It's Been about 400 miles and when it's cold (First start-up in morning) The shifts are firm but as it warms up, the firmness seems to go away. Whould the valve body not making good contact with the trans cause this?

 

are you sure you have enough fluid in there?
did you add the deep trans pan?

 

Have the Moroso trans pan and fluid level is good with the engine running.
