Th350
 

My friend gave me a free th350 with a torque converter, and some oil lines that go to i oil cooler i assume and what seems to be a kickdown cable, but it looks short. This is going into my C10 which currently has a manual 5 speed. What parts do i need in order to swap in the automatic, i have a automatic column in my truck already, theres a tab on the engine side of the firewall for what i think would be linkage but i dont have that either.

what kind of flywheel or flexplate do i need?

ok ... do you play the lotto??
I'd save up and rebuild the th350 before you install it.. if this is your only vehicle..
if not roll the dice..
not knowing what they did to the automatic crossmember that's under the truck(if it's still there) when they installed the 5 spd.. I'd see if you can get a pic of the auto crossover to see if whats under your truck is what you'd need or if you need to find another.. the shifter linkage... someone must have it.. bobs409 is parting out a truck pm him it might have what you need..
as far as the kickdown cable if the engine end is still there it's fine.. they are not all that long... you will need the bracket the cable goes into on the intake of the engine if it was removed when they changed over to a stick..
you didn't say what 5 spd is in the truck but figure on needing the yoke that goes into the trannys tail shaft housing.. and if the tranny lenth are different a new drive shaft..
my guess is you have a t5 out of a mid 80's chevy truck that was behind 305's in 2wd short bed trucks..
speedo cable should work.. but you may have to change the gears for the speedo..
they are color coded.. pull the side piece that the cable screws to and see whats there.. then look up what gear end gears that color is for.. change if need ed..
good luck..
most free th350's are cores... unless you knew the car/truck it came out of and knew it worked well.. I'd rebuild it.. the kits are cheap and there is moch online to get you through it.. it be money well spent...
me I'd keep the 5 speed.. unless your knees are say'n no.. they make aftermarket ones that take more power.. tho if a daily. and see's traffic a stick can be a p.i.t.a.
good luck

The tranny i have now is a 5lm60, the th350 was bolted to a 355 in a s10blazer, this is not my only vehicle. Next weekend when i have time to pull my old 5 speed to rebuild it cause somethings not right i'll take a look at the th350, im pretty sure it will bolt up to my crossmember. Im just not sure as to what flywheel and flexplate i need to get, the linkage i can probably get from pull a part or summit racing.

Re: Th350
 

depending on what tooth flywheel starter rings on it now 168 tooth or 153 will dictate what flexplate you use.. summit or a u pick it. the linkage a u pick it. summit will only have stuff for aftermarket cable shifter (think b&m )

http://www.napaonline.com/Catalog/Ca...RecType%3aA%29 is the one i used with the starter for a 78 c-10 btw you will need shorter flex plate bolts

Re: Th350
 

Wait i thought i just need a flexplate, or do i need a flexplate and a flywheel or just a flywheel?

Re: Th350
 

for an automatic you need a flexplate I said to see what tooth flywheel is on it now, so you get the same tooth flexplate and can use the starter you have now..

if the flywheel in the 5 spd is 168 tooth and you by a 153 tooth flexplate you'll need a new starter.. unless you have an aftermarket mini with both bolt patterns..
