Has anybody made a car OD, either t86 or t89, work with there trucks? what did you do? how did you fix input/output problems? Anything else that might help?

Well I have the same 59 /292 sitting in my shop with thr heavy duty 3 speed on it and was thinking the same thing as I have a 56 passenger car overdrive in another car . the difference I saw was the heavy duty 3 speed has o bigger input shaft and it is about 3/8 of an inch longer . I thought I could just use a smaller passenger car clutch and throwout bearing along with a car clutch arm . In my project I would just get a drive line shop make me a new driveshaft . Thats all I can help you with , maybe somebody will come along and help both of us .
Jim, You could swap the input shaft/gear to a LD truck input, as long as the gear count is the same as the car trannie's. I don't know if they are the same tho.

I thought I could just use the passenger car flywheel and clutch set up . The trans will bolt to the housing , the housing is only about 3/8 of an inch deeper than the passenger car , but I need the 59 pickup housing for the rear mount legs . Is there something I'm overlooking ?
I don't think the input will reach to the pilot bearing, but I'm really not familiar with Late Model stuff. To be honest, if I had your setup, I'd be doing a T5 swap; much better tranny, just have to work out the shifter.

CBASS139 , I never meant to hijack your thread yesterday and I'm not sure you got the information you were after . So I will see if I can get this to the top for you . JIM
No problem Jim, I thought maybe more guys had done this because the car OD seems to be more available. Hope somebody will see this that has done it and can step me through it.

the car/truck OD's are the same, there are three models R9, R10, R11 with the R11 being the newest and the strongest (4 sun gears).
The trans mission has to be made/adapeted for the OD unit - there is an extra hole in the rear side of the tranny that allows the reverse lockout to operate.
Then you need to round up the electrics and hook it all up.
You may need to modify uour drive shaft.

I have rebuilt a 56 car overdrive , so the insides are not new to me .I'm not sure what all cbass139 needs to know . But what I need information on is . I have a complete 56 car overdrive , with flywheel and all clutch conponents and car clutch housing . the pickup housing is about 3/8 of an inch deeper , so that makes the input shaft a little short compared to the larger and longer pickup heavy duty 3 speed that is in it now . transmission bolt paterns are the same , but I need to use the pickup housing for the rear engine mounts . I may be able to have a bushing made to take care of the 3/8 in difference . Is there any other problems I havent discovered yet ? I don't want to try switching the input shafts , overdrives are not easy to overhaul .
Swapping the input shaft is not that hard, although on some 3-sp's you have to drop the cluster gear to get it out. But like I said earlier, the key is whether the main gear has the same number of teeth in a car and truck tranny. To do it really right, you could get a truck 3-sp and swap everything into the OD's case, using the OD main shaft, and all the gears from the truck tranny. As Dick said, the case for OD's has the extra hole, and the main shaft is the only other difference compared to a truck OD.

Well maybe thats the way I should be thinking about as I have a good working truck three speed , it just needs overdrive . It's just that the older I get , the harder it is to get my fingers in those tight places in transmissions . L.O.L. OK , Am I understanding this right . I can take all of the overdrive parts tailshaft , overdrive adapter plate , mainshaft and install in the truck three speed . Keeping the truck input shaft and all of the truck gears ,misl parts that are inside the truck transmission main case now ? The reason I ask is I have been told someplace other than F T E that the overdrive transmissions have there own unique main case that is different than a standard three speed . It would be great if I was told wrong .
The difference in the main case is the extra hole for the reverse lockout.
It can be drilled in a non-OD main case.
I think I have the info somewhere in my 15,000 or so truck files.
