TH350C Longtail trannie
 

Just got back from Pa. visiting my brother and his new wife. Looking to do a little wheeling and dealing, I was on the hunt for a trannie for the SWB. My sister-in-law's uncle ends up giving me (free) a TH350C in need of a rebuild. Unfortantely, it is a long tail. I know this has been covered before but, I believe I will need a short tail in my truck. Is this true and should I trade this for a short tail?

The 350 nonlocking trAnny that came out of my dads truck had 9" long tail on it if that helps any

Re: TH350C Longtail trannie
 

either will work but the driveshaft will have to be correct for the application

Re: TH350C Longtail trannie
 

My truck came with a 350 longtail and to swap to a th400 I had to move the crossmember back and get the one piece driveshaft lengthened 3 3/4" for the 400 to work.

Re: TH350C Longtail trannie
 

I have the shorter one in my swb and the long one is usually on a long box with 1 pc dr.shaft from what I,ve seen on my stuff

Thanks guys. You have been a big help. I need to go to the pick and pull and grab a new trannie crossmember anyway so, I will check and see if they have a short bed up there with a long tail and measure the drive shaft. I have a feeling I may swap this for a short tail

Re: TH350C Longtail trannie
 

my dad has an 84 c10 swb right now that has a long tail th350 non lockup, and we had a 76 with a 3 speed on the column(manual and it was the same size as a th350 short tail, so again either would work just need the driveshaft to fit said trans. to use and maybe move crossmember.

Re: TH350C Longtail trannie
 

I guess now is the time to decide whether I stay with an automatic or convert it to manual and throw the Saginaw out of my 68' Camaro in there. Too many decisions and not enough money. I know it's probably going to cost more to rebuild that Saginaw than trading this long tail for a short tail and having it rebuilt

Re: TH350C Longtail trannie
 

Imho the Saginaw would not be ideal for a truck. My 86 swb came with a th350c longtail and it made the swap to a 700r4 easy and driveshaft did not have to be changed.

Thanks HOGDADDY. I have the drivetrain out of an Olds Omega in the truck right now. The PO torched the cross member to make it fit (Olds 260 & TH200). It sit back about 1" from where it should be. I may just use the long tail to avoid myself some problems

Re: TH350C Longtail trannie
 

the sgainaw should be the exact same length overall and same driveshaft as a short tail th350. As for having a truck with a short tail trans. and wanting to put in a long tail you can have the ds cut and re balanced, shouldn't cost more then a hundred bucks, or find one in a junkyard for cheap.

Re: TH350C Longtail trannie
 

Since the th350c needs to be rebuilt, you could have the tail shaft and tail housing swapped during the rebuild.

Re: TH350C Longtail trannie
 

Local shop can do the rebuild in 24 hours with a new torque converter for $ 500. They will give me a one year warranty on it. I may just get the drive shaft cut down & balanced for another $ 50 bucks. I guess I need to save up some money but, paying for daycare for my girls is the top priority right now
