Hi i have 2005 35th 5A/T and i want to put a 3.5 gear set up or more, what do i need to do that, i had reading about that and i think i need to do some mod?
THANKS!

 

You can't do a straight swap without an entire rebuild. They're different thicknesses. Its easiest to source an entire replacement pumpkin from a 6MT.

 

How much is it for the entire pumpkin in use, how much can i sold mine?

 

Used 3.5 pumpkins usually go for $400-$500 + shipping to buy a used one straight up. A lot of times somebody who is going FI and has a 6MT will want to get a 3.3 diff to replace their 3.5 and will usually do a swap + cash.

They are few and far between in the classifieds and in ebay. I know Jim at Turbo Toys usually has some 3.5 pumpkins laying around. He's a vendor here so you should be able to search for his user name - Turbo Toys or TurboToys (I think) - and send him a pm.

 

Like everyone is saying, just swap out the whole pumpkin. Best mod Ive done!
