  • Engine: Engine & Trans

    I have been having Overdrive problems with my 6 cly 57 Silver Hawk, mind you I have driven it 58,000 miles Now I'm on my second trany, and it has gone again. So I am looking at at a swap 92 Chev 305 complete with auto trans complete wiring etc. Any suggestions? Would be much appreciated by this cool dude that knows nothing about this.

    Well... I could tell you what I did but it's all been documented here:

    I have a '59 Silver Hawk (350 Chevy/700R4) and used a non-electronic transmission. I never did like the electronic converter because it hunts/searches sometimes. Also the lock up converter only gives you 1-2 more MPG. But you should build what you want/like although many members will tell you to leave it all original. You didn't say, but I imagine you're going with an overdrive trans???

      Yes I want an overdrive transmission, I converted the old 6 cly engine to a brand new Cathcart engine twin carbs electronic egnition, duel exhaust different cam, a stage 4, extra 50 HP. nice engine , but now two many trans problems, and I plan on taking it to the next annual meet. Cathcart did have an adaptor plate available when I got the engine but I stuck with the Stude trans , now I wish I had put in the S10 trany.

        When you changed to a high horsepower engine did you also change the light duty 6 cylinder tranny?

        I'd guess not, and maybe all you need is the heavier duty stick tranny.

          I wouldn't think a hopped up Champion engine would be THAT hard on a T-96. What type of failures did you experience?

          I also wouldn't think think that redesigning the car would be more straightforward/easy/simple than figuring out why the transmissions failed.

            I agree with Roy. Unless the transmission was already worn out when install or if it was treated roughly, it should not fail so quickly. What type of failure have you had?

              The issue is lacking info.... You state overdrive problems, then mention 2 failed transmissions. Which is it ? OD problems, straight 3 sp problems, or both ??? The only way I see 2 trannys being toast is the pedals' pusher...

                Each time I have lost the over drive portion, I still have had first ,second & third gear but no overdrive. I had the system rebuilt several years ago, and every thing worked well . No it is not being pushed hard. But since that trany rebild I have driven it 15,000 miles. I was going to take it to St Louis for the Annual, but something was nagging not to , and I'm glad I did not, as I would have only made it into North Dakota.

                  So you just had a loose wire, blown fuse, wet with oil and bad seals, Solenoid, burned out Solenoid or WHAT?

                  No Overdrive shift in O.D. Mode freewheeling only, is most always a non-functioning SOLENOID for whatever reason in 90% of cases. No need to discard the entire Trans.
