Anyone use this ? .

it appears to be *much* easier to install , rather SPENDY though ! .

Thoughts & comments please .

TIA ,
 
Re : THANX !

I discovered the TH200r4 from a Corvette is a direct bolt in and some even have
a four hole rear mount plate so I can use my TH350 cross member , , this will cheaper yet (under $600 rebuilt & installed I'm told) so I'm leaning this way right now .

I see many have looked at this thread but no comments ~ I'da thought overdrives would be very popular with both Hot Rodders and the stocker guys....
 
Th200-4r

O.K. , I googled this and spent hours reading and taking notes , I think this is the right way to go , now to find the core as there's quite a few different ones to choose from .

Apparently the pre 1988 Model year ones don't need any switches to operate the lockup TC , it's done internally , just apply 12 volts to one pin and you're off & racing .

GM makes a DP , DT brake light switch you run the 12 volts through so as soon as you touch the brakes , the lockup cuts out .
 
Thank You

Russ ;

I'd forgotten what GM Vehicle it came off of so now I know where to get it :) .

Looks like I'm going to go with the GM TH350-C , that's no overdrive , just a lockup TC on a built TH350 three speed slushbox .

Only one wire hookup , I used to have an old British Leycock overdrive switch floating around , I'll use that as it looks neat and is definitely period correct .

How can I best clean the tranny cooler in the radiator with the radiator in situ ?.

TIA ,
 
I Pulled TheTrigger

And ordered up a Phoenix Transmission rebuilt th350-C with 1,500 RPM lockup torque converter just now .

I can hardly wait to get it in the truck .

:p

They're swamped as it's nearly spring so I have to wait 3 ~ 4 weeks :o .
