Another Transmission thread plus gas gauge and speedo

[bbqfan5909]

Hello,

I am having problems with a few things and really dont have much free time to trouble shoot. Any help would be greatly apprieciated!

First: Have the same old problem with hard shifts and high rpms. Any pictures showing the vac line replacements and modulator?

Second: Speedo and gas gauge does not work, cables broken and where should I look?

Thanks everyone,

Casey

Speedo: is the odometer working? if so then cable OK and head is bad.
Gas gauge: check ground on sending unit, common for rust to break ground.
Just a thought

For the shift problem, start with the rubber vacuum lines on top of the engine below the air cleaner. I replaced all those on mine last week (the old ones looked like they were made of sponge). Parts cost the princely sum of $6.23 including tax, and I had lots of hose left over when I was done.
I gave it a test drive after doing that but before moving on to the other parts, and found that my problem was completely cured. Went from hard shifts at 25 and 50 mph, to smooth shifts where they should be.

Download the -34 manual in the Resources section and read it before you start. There are pictures and good explanations of the procedures.

Cheers

Unscrew the speedo cable end from the trans and have someone turn the inner cable with their fingers you look to see if the speedo moves if it does then the problem is in the gears in the trans if not then pull the inner cable out and inspect, if thats good then the speedo unit itself might be the problem. just a thought.......
