Turbo 350 Kickdown Cable Issues - Need Advice!

Questions and Support
1

I’m currently working on my Chevrolet with a Turbo 350 transmission, and I’m having some trouble with the kickdown cable. I’m not sure if it’s functioning correctly, and I could really use some help.

What is a Kickdown Cable?

The kickdown cable plays a crucial role in the operation of the Turbo 350 transmission. It allows the transmission to shift down a gear when you hit the throttle, providing that extra power when you need it. If it’s not functioning properly, it can lead to performance issues and unresponsive gear shifting.

Issues I’m Facing

  • Delayed Shifting: I’ve noticed that my car isn’t shifting down as quickly as it should when I accelerate. This can be frustrating, especially in situations where you need to merge onto highways.
  • Inconsistent Performance: Sometimes, the kickdown works as it should, and other times it feels like it’s not engaged at all.
  • Cable Condition: I’ve checked the cable and it appears to be in decent shape, but I’m not sure if it needs replacing or if it just needs adjustment.

Questions I Have:

  1. How can I tell if the kickdown cable needs replacement or if it’s just misadjusted?
  2. What are the steps to adjust or replace the turbo 350 kickdown cable properly?
  3. Are there any specific tips for purchasing a replacement cable if I go that route? I want to ensure I buy a good quality part.

Additional Info

My vehicle is a 1978 Chevrolet Camaro, and I really want to get it running perfectly again. If anyone has any experience with this sort of issue, I would love to hear your thoughts or any resources you could share.

Looking forward to your guidance and thanks in advance!

I’ve had my fair share of Turbo 350 kickdown cable issues. The installation can be tricky, but I found that setting the cable length before attachment really helps. Anyone else experience this?

That’s a great tip! I also suggest checking the cable routing. A smooth route makes a big difference in performance.

I battled with the bracket alignment when installing mine. If it’s off, the kickdown won’t engage properly. Double-check those mounts!

So true! I learned that the hard way. It’s amazing how a small fitting can affect your entire setup.

I recommend getting a new cable if yours is old. They can fray and cause issues you won’t see until you’re on the road.

Exactly! Can anyone suggest a reliable brand? I’m looking to replace mine before it gets worse.

When you install, make sure you properly adjust the linkage. If it’s too loose or tight, you can end up with sloppy shifting.

Great point! Additionally, I always suggest a test drive after making adjustments. You never know until you hit the gas!

I had a tech tell me once, ‘If you’re not willing to get your hands dirty, you won’t enjoy the ride!’ Always remember to have fun with it while you work.

Absolutely! Humor can really lighten the mood during frustrating projects. You’re all in for a ride!

For those who have done this before, what’s the biggest pitfall you wish you had avoided? I’m planning to tackle mine this weekend.

Not labeling my old connections was a huge mistake! It added extra time to my install. A simple marker would have helped!

Remember, patience is key! That cable can be a puzzle. Take your time, and you’ll figure it out; it’s a learning experience after all.

I’ve been dealing with Turbo 350 kickdown cable issues too! To adjust it, make sure the cable is tight enough but not overly stretched. A good starting point is to ensure the cable has about 1/4 inch of play when you pull it. It makes a huge difference in shifting smoothness!

16

I totally relate! Has anyone tried adjusting it while the engine is running? I read it might help in finding the tension sweet spot for better performance.

17

It’s true! I’ve adjusted mine with the engine running, and it felt a lot better. Just have a helper to press the gas pedal to ensure it engages correctly while you adjust.

18

I’ve heard about some folks who suggest using zip ties to hold the cable at the right length temporarily while testing. Anyone else done that? Does it really help with finding the right setting?

19

Lol! That sounds hilarious but practical! Just make sure you remove the zip ties after you’re done testing! Safety first!

A good tip is to observe your RPMs during acceleration. If they drop too soon or if shifts feel sluggish, it’s time for a tweak. Always fine-tune while driving for optimal results.
