TURBO 400 Rebuild Questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

setelec 73 · 04-30-2009, 10:36 PM

I am fixing up a 73 chevy 3/4 Ton, and it turns out that my transmission case has a crack in a place that cannot be welded. I was already planning on have to have the transmission worked on but now am going to end up with another case and having the trans rebuilt. Just curious if there is anything anyone reccomends that I ask the guy to do? I asked about a shift kit and he said he could just drill something? to allow more fluid to pass? I have no clue about any of it! So anyones input would be greatly appreciated. .. i should say that the truck is stock. 454 Big Block and no plans for serious motor upgrades but hopefully get a cabover camper for her.

the thing i would add is a transmission cooler if youre planning on a camper.. and that is external of the tranny

I apologize for not stating that It does have a cooler in front of the truck. My Grandfather hauled a fifth wheel for a while. Hopefully it is still good dosent look that old? Thanks for the replys i appreciate everyones time!!!!

So i have now got 2 estimates for the rebuild. I have one guy that wants 900 to build and another that wants 1250.00 and says that is with heavy duty parts?? and a shift kit. The 900 estimate is pretty much a stock rebuild but will put a shift kit in for me?? These are both with removing and restoring trans. Also the new case..Please help with any ideas or suggestions. Thank You

Not knowing either of these people or having seen the quality of their work makes giving input hard. Personally from the sound of it someone claiming to use "heavy duty" parts in a heavy duty tranny sounds like he is trying to justify his higher price. That's the impression I am getting from what you have stated.

Thanks Joe.... appreciate the responses.What do you think about a shift kit?

I'd ask the tranny guy thats gonna build it for his input. If youre gonna put a cabover on it you dont want it to shift to hard or all your stuff will be everywhere. Not being a tranny wiz myself I would run it by him, drilling a extra oil circuit is a milder way to improve the shift strength if I remember right.
