1997 chevy 1500 cheyenne Manual Transmission

Hi,

Contacting chevy directly, might be your best option to getting the diagram that you're looking for. They should be able to email you the diagram. Thank you.

Does the pedal go to the floor?? If so it is the master and the slave, they are replace as one unit of repair. If the pedal is very stiff but doesn't go to the floor you have a failed clutch.

Sorry no diagram. But here is how it works. In the start position(Power) the wire goes to the start fuse, from the fuse it goes to the clutch pedal switch. Push the pedal and it goes to the starter relay. On the other end is ground. If it is good it pulls the relay closed. On the closed end is battery power to the starter.

Check the clutch start switch above the clutch pedal , look up under dash . Yellow wire going in, purple coming out ! Yellow should have battery voltage with key in start position. The purple should have battery voltage with the key in the start position with the clutch pedal pressed down .

Any chance clutch disc installed backwards?

Will it physically fit? yes. Will it be a direct replacement any everything hook right up and plug right in? If we are talking about an automatic then no. 1994's wiring was completely different than the 1997. Can it be made to work? possible, but I believe it would be more trouble trying to make it work than if the correct transmission were located and installed. If it is a cost issue where he has a good trans out of a 1994 he might see if a salvage yard will do some partial trading for the correct trans.

You may have a bad clutch master or a bad slave cyl. To bleed the system you need to find the bleeder screw under the truck where the slave cyl enters the bell housing. Make sure the master is full of fluid. Note-some reservoirs will have an rubber cup insert inside which will make it look full . If so take it out.
Open the bleeder at the slave cyl and watch as the fluid comes out to see if there is any air. After a while, close the bleeder and pump the clutch pedal to see if it is starting to work. If not, repeat opening the bleeder again etc. If you get a little pedal, then hold the pedal to the floor and have someone open the bleeder. Close the bleeder and repeat until you get a good pedal. If you have no success you may have a bad master that is not producing pressure.

More than like you mean the clutch pedal just goes to the floor. If this is the case the hydraulic clutch has a failed part, that would likely be the Master cylinder on the firewall under the hood or the slave cylinder down on the transmission.

The clutch system has air in it.

If hydraulic actuated mechanism, loss of fluid, defective master cylinder or slave cylinder at the clutch. Missing pin or other part between slave cylinder and clutch arm. Loose or broken slave cylinder mounting. Missing pin or broken part between pedal and master cylinder. If mechanical linkage, look for broken components or missing pins at moving joints. If you tried to shift into gear with engine running, you may have damaged the transmission gears.
