looks like you do have somewhat of a transmission leak. Did you check the fluid level with the car idling in park? your kickdown linkage is hitting a hose clamp on one of the trans cooler lines in the last picture. this line should be all metal until it gets close to the radiator. I have bent a piece of brake line to make a new one. the kickdown adjustment should not have effect on it going into forward gear, so that most likely is not your problem. although it does need to be adjusted properly. you do have a shift linkage bushing that looks like its not in its place. i would check the shift linkage adjustment first.

Yes, but it may be too late. Black transmission oil = probable dead transmission. :-(

Use Dexron automatic transmission fluid.

Your tires are about 25" diameter

Original tire diameter if they were 6.95 14 is also 25"

So you're fine with the tires.......

If you have access to the parts, drop the pan and do a fluid and filter change. Sounds like a the friction material has disentegrated off a band or clutch pack.

Thanks emsvitil and Jeb for the post.

here are some pic of fluid. the level is taken as per procedure (Lever on N and run for 5-10 min)

can you tell me is this color okay? some bubble i have notice can see in oic below.

Image

This is the carb setup i have it is stromberg BXUV

Image

I tryied to put car in reverse and car move fine. then put on D i can feel the car take jerk to move front then when pre accelerator it move very slow looks not power engine reves but not getting power in wheel. what you guys think should i addjust front bend ?

before addjusting i am planing to remove transmission oil and drop the pen and clean the filter (new filter is not available already confirmed)
and then fill new oil and try if not work do the front bend adjustment!

any suggestion guys will apriciate.

sorry for my english :)

That color doesn't look bad, but that doesn't mean the transmission is ok.

Another quick check is to smell the fluid. If it has a strong burned smell it's time to rebuild the transmission.

1. Car not running.

2. Have somebody press the accelerator to the floor, wide open throttle.

3. The Throttle Valve Lever on the transmission should be all the way back, toward the rear of the car. If not, adjust it so it is.

If this can't be accomplished, you will need to modify the kickdown linkage so it moves the throttle lever all the way back, or install the correct lever on the transmission. If you can grab it with your fingers and move it further, it isn't adjusted right.

Once you have the Throttle Valve, "TV", adjusted, change filter and fluid, and hope for the best!

The throttle valve adjusts line pressure. At idle or partial throttle, to make shifts more comfortable and earlier, the pressure is lower. At high throttle settings the pressure is higher and will delay upshifts or cause down shifts.

Remember he said he couldn't find the trans cooler lines? I'm wondering if someone removed them,and blocked off the fittings.

The cooling looks modified by previous owner. now no more cooling from radiator a rubber hose connected from front to the back of transmission.

one more issue here in Pakistan very good mechanic for Manual Trans (1960s) but unfotunatly no one trained for old type auto transmission. all are talking sensors etc....

what is the good replacment of A-904 to manual transmission? any suggestion. A-904 parts are also not available in Karachi.....

Thanks

There's the reason the transmission failed-NO cooling for the oil! Does the transmission drive forward fine when cold, and just slip when hot? If it only slips when hot,maybe it could be fixed by installing a trans cooler. If it slips even when cold, it is ruined. The rear clutch pack is engaged in all forward gears, but not in reverse, and is probly the item that failed.
