TH 350 trans swap
What has to be done to a 1986 TH350 to replace a 1976 TH350?

Re: TH 350 trans swap
No such thing as a 1986 turbo 350, they were discontinued in 81-82

Re: TH 350 trans swap
I had an '86 C10 for my first vehicle and it had a stock TH350C in it. Good transmission, '86 is the last year for it as far as the trucks.

Re: TH 350 trans swap
My 84 had one.
Was a turbo 350C. If you do have a 350C it’llhave a Lockup converter. Last year for them was 1986. Last edited by geezer#99; 06-28-2018 at 09:01 PM. |

Re: TH 350 trans swap
How do you identify a 350c from a regular 350?

350C will have a solenoid on the side near the shifter shaft.
