How can an automatic transmission be fixed without being rebuilt?
Help
If you really do want help then you need to give people some information.
If you’re having serious problems then the simple answer is “it can’t” or perhaps, “you buy a new one instead.”
Better yet, post some info - what is the year make & model of the car? How many miles are on it? Has the trans had regular, recommended service? Have you checked the fluid? How does it look and smell? What is the transmission doing that seems to be a problem? Have you taken it anywhere? If so, where, and what exactly were you told? Is your check engine light on?
No one can answer the question you posted.
In D and 2 the transmission lurches like it doesn’t know what gear to go into. In 1 when starting the engine revs, then the car kicks into gear and goes. Is there any thing that can be done, other than rebuild the transmission>
looks and smells ok.
Even though you haven’t given detailed information I would say that a transmission can rarely be fixed without total rebuilding. In the odd cases an outer component of the trans can be replaced and solve the issue - which is likely in newer cars. In older cars, with luck, you can replace the “Throttle Body” or adjust the bands and the trans will seem like new.
However, if you are curios of a quick fix I’d say don’t postone the inevitable. If a dishonest mechanic says that he fixed the problem without having to rebuild, be cautious and ask for a warranty on the fix.
You mention the fluid looks pink and smells good but you don’t mention if the level is at the full line with the engine running in park after a warm up drive of 10 miles and on a level pad. Also touch the oil and dip stick to assess the temperature of the fluid. If the fluid is excessively hot, you may have a friction element slipping.
I assume you have a AOD or possibly an AOD-E. The best approach is to have a qualified transmission technician run a diagnostic on the transmission. Have the technician experience the problem. With either you or he/she driving, elicit the problem and bring it to his/her attention. If this transmission is computer controled, have the computer scanned for codes. Do a line pressure check at idle and stall and while driving when the problem occurs. Have the technician drop the pan, assess the debris, remove the valve body, and do an air pressure check on the clutches and band servos. If the air pressure check is okey, have the technician assess the freedom of the valve spools – do they move freely and snap back to home position. If this is an AOD have the technician remove the governor and assess it for freedom of motion and integrity of any O-rings/slip rings. If all is in order, reinstall the valve body, install a new filter, refill the transmission and assess the results.
After having gone through a thorough diagnostic, the technician should be able to tell you where he thinks the problem lies.
Good luck on this. Post back with what you find.
