EL CAMINO Clunking auto trans under load when warm and low rpm

If you plan on keeping the 305 I'd slap a T5 in there and rock it.

What's the eighth digit of the VIN number?

It's an H. I can get some pictures of the pan once I can reach the lift in the garage. I'll update the topic with those once I have them.

That's across the board. No G body came with the TH700R4, only the B, F & Y bodies for passenger cars. Look at the PDF which is for the MVMA (Motor Vehicle Manufacture Association) passenger carspecification form for Chevrolet Monte Carlo 1GZ37 & El Camino 1GW80. This was filed by the American manufactures to show specs & features of vehicles for the specific production year. The MVMA was active 1911 to 1999.
Here's the link to a thread I started that will have all the info that includes what transmissions was used with each engine RPO & Chevy A/G model.

This might not be helpful to the BOP guys but I'll share this with everyone so anyone looking for Chevy info or cross referencing shared details that the BOP cars shared. I'll start with the Malibu, followed by the El Camino, end with the Monte Carlo. Malibu

Hey there guys, I know we've touched on the things to check but as I mentally work up the courage to get myself into more of a pickle, I'd like to discuss my first steps in diagnosing this issue. I would imagine the first is pulling the pan and looking at the condition of the fluid and for any clutch material or foreign pieces. Second, I would do the tv cable adjustment again, in case the mechanic didn't do it correctly.

What's the next step after this? Is it checking pressures? If so, what type of gauge to I need to ask Amazon for? If it's not pressures, what is it?

Thanks to everything for the help so far. I'm hoping to find something I can resolve myself and the only way to know is to get to work.

If the TV cable not set correctly trans will burn up in no time. If your running stock engine and stock carb. You should be fine. The carb linkage was designed for what you have. As long as you are still running as it came from factory.

Pull the pan and see how much and what type of crud in pan.

For the gauge. Just the harbor freight fuel pump kit is ok. Your port is 1/8NPT

Two details that matter 300PSI minimum and a hose long enough to reach from the test ports on the transmission to somewhere you can see the gauge easily when in the drivers seat.

Thanks for sending. This morning heading out the door didn't have a enough time to go into it further

While waiting on my pressure gauge kit, I'm trying to figure out what needs to be recorded for a test. I have two questions concerning the manual's instructions.

1) It states minimum and maximum TV tests. Is minimum adjusting to as little cable showing and maximum adjusting to see as much cable as possible?

2) Why does the repair manual make mention of the cooler ports on the trans, do they expect me to do something with them during the test?

 

[ELCAM]

Minimum is the TV cable installed and set as it supposed to be.

Maximum is with the TV cable fully extended, remove the end of the cable from the carburetor and pull and hold the cable fully open with a spring or small bungee cord.

You will not be messing with the cooler lines during the pressure tests.
