Have a ?
I have 2002 chevy Marlo Carlo ss with 3800 in it and was wanting to know if a transmission from 01 Grand Prix with a 3800 super changed would work in my Marlo Carlo

The question is - why do you want to do the swap?
It will work, but there are a couple important differences: -the sprocket ratios are different. The HD trans has a lower ratio (similar to putting a numerically lower rear end in a rwd car). As such, the pcm tune should be modified to account for this. -the differential is different, and you will need a different passenger axle to accommodate -the torque converter diameters are different (ie the HD converter won't bolt up to a non HD flexplate, they need to be matched) If the intent is to do this for better strength, I wouldnt bother. You can upgrade the main part that's heavier duty (the diff) on your existing trans if you really want to. |

So this ^^^^ is something Ive wanted to ask for a while..

I don't see a regular trans failing notably earlier than an HD trans on a supercharged application, especially with just bolt ons. For any kind of decently modded 3800, if I was pulling the trans, id definitely be putting a built one back in though. |
