How do I recognize the 350C ? Is that the same as previously posted. My son has a rebuild kit for a 350 and it tells him something about an electrical connection on the drivers side being a 350C. Any input would be helpfull, thanks

the information in front of you is correct... electrical plug on the drivers side.

look at the input shaft = that would be where the converter is located , shafts with splines on them. The inner shaft rotates. the t-350C has a polished end on the input shaft... there will be a rubber O - ring too.

NEXT>> = to ID A T-250C trans. Look at the cooler line fittings area.. passenger side. Look for a threaded stud with nut that protrudes from the case. That is a t-250C trans = weaker , low performance.

Thanks alot. We were going to put it on a chevy 350 and put it in a Yota 4X4. I think we will just go to pull n pay and get Turbo350 to rebuild not the 350C we have.

hi there this question is asked many times a month, heres a thread from a few days ago about the th350c, i posted pics of my th350c trans so you can physically see the input shaft difference vs a non C 350 trans. and see the electrical connector on the side.

here:
TH 350 trans/varifit bell/lockup?

if there is no C letter cast on the pump housing or anywhere on the trans case then that means its not a converter clutch model

th250c has 11 bolt pans vs. 13 bolts on the 350/350C trannies

does yours have a 4x4 output shaft ?

i need a torque converter for one with gas engines only.

looking to buy one.

stock preferably.

good luck

I would suggest you check your internet source of information again or you mis-typed that statement..

The t-250C , t-350 and t-350C all use the same pan with the same bolt count of 13

Crosley is correct.

ALL 250, 250C, 350, 350C, & 375B transmissions use the same pan.

1976-1979 TH200- No modulator, 11 bolt pan, no 4X4's, normally has "Metric" on the pan. Lock-Up has electrical connector on driver's side of case above and behind the gearshift linkage.

The way the info is written on this particular site, it would be east to mistake the specs given for the TH200 to also include the TH250C.
