I'm guessing it may be a t-5 without the overdrive? I havn't been trying real hard to find a t-5 but I'm wondering if that t-4 may be ok to use instead. I have a '49 with a inline 250 ci, sm420 4 speed trans and a 3.90 rear out of a '58 pickup right now.

That is what you are after. I dont think they put the t-4 in the S-10 after about 83-84. If you can see the trans. check the knob to see if it has 5 speeds. Try to shift to o-drive. It is way over to the right & down. Over to the right & up is reverse. If 5th is blocked out then it is a 4 speed. I just came from a pik your own parts type salvage yard & there was 2 there. One was already out laying on the ground but I dont know what it came out of. It had the shifter way in the back but it had the fine splines & mech. speedo. The other one was still in a 85. The shifter felt snug on it. If anyone in the K.C. area wants to know about them e-mail me. [email protected]

Some were simply T5's with the OD gears removed, however most do not have the right tail shaft or internal shafts. They make good donors for a front case for a T5. Other than that, they are not worth much. I would NOT replace an SM420 with a T5. With your 250, I would be looking for a NV3500 from behind a 4.3 V6 in an S-10 Stronger than the T5, and will bolt up with NO modifications.

Would the shifter end up in the right location? | | | | | Joined: Aug 2007 Posts: 1,859 Grumpy old guy playing with trucks, cars, and boats | | Grumpy old guy playing with trucks, cars, and boats Joined: Aug 2007 Posts: 1,859 | Yes and Yes with the 250 that you have.
