I have changed filter to discover that the large speedometor gear is broken and bits were found in trany pan and filter. Replaced filter, trans fluid and removed what was left of the speedometor gear that was around the trans axle. I do not see how this will effect shifting but if it does then please let me know? I am definately a trany guy. But the owner is 68 yrs old and cant afford a new car. The gear that was bad is not the gear conected to the spedo cable but the gear that drive the gear for the spedo cable (POLYPROPOLENE GEAR)

Overdrive would not engage at 35+ mph. Took trans pan off, removed filter, dropped valve body out. Found broken snap ring on overdrive servo. Removed and replaced snap ring. Opened valve body and found 1 of the broken pieces stuck in a valve. Replaced all valve body gaskets. Put valve body back in with 95 in/lbs torque. Put in new filter. Pan on with 120 in/lbs or 10 ft/lbs. Refill with trans fluid. Run through gears. Lower vehicle. Test drive.
Assuming there is no shift solenoid problems,(1-2 solenoid OFF in 3rd gear and ON in 4th gear!) Then I would say that your transmission is broken but more often than not, is repairable. First order of business would be to remove the transmission drain pan from the bottom of the unit. Loosen the attaching bolts slowly and in a circular manner, allowing the trans fluid to drain into an appropriate size pan. Remove the last of the pan bolts, and without spilling the last of the fluid, remove the pan from the trans. Carefully inspect the fluid for the presence metal either as chunks or suspended in the fluid. Also, smell the fluid for any "burnt" oder. The more metal you find, the more money to repair the unit. After component repair, be sure all trouble codes are cleared.
Check trans fluid with engine running - if low, top off. If fluid level is fine then try changing the transmission filter located inside the transmission pan. You may also have an issue with dirty trans fluid - if it is not pinkish but brown then have a transmission power flush done, then change filter.
The pan needs to be removed to change the filter. Use a large pan to catch the oil and remove the pan bolts slowly or you will have a big mess. After you have replaced the filter, Clean and reinstall the pan using a new gasket. This should stop the leak if the old gasket was bad. Dont over tighten the bolts. Measure the oil drained and install the same amount of new fluid through the trans dip stick. Start the engine and shift through all the gears with brake on. Check fluid and add if necessary. Not a bad job, just a little messy..
jack van, use safty stands to hold up, put a pan under trany pan to catch fluid, remove blots holding pan,fluid will start to leak out.leave the front bolts for last ,that way theoil leaks out the back,after all bolts are removed then take pan down, pull filter out,install new filter with gasket ring for neck of filter, clean pan and trany, install pan gasket and bolt up.use cross pattern to tighten,just tight alittle dont crush gasket. put in 4 qts,run engine and run through gear, check fluid and add acording to dip stick,hope this is helpful.
to change your tranny fluid and filter is relativily easy i will tell you step by step here.
1. raise the vehicle and support it with jack stands
2. get a large drain pan
3. locate the transmission oil pand and losen all the bolts removing the rear half of the bolts only and just losening the other bolts to keep the pan held up but allowing it to sag on the rear.
4 be carefull because in this step your likely to get a bath in tranny fluid. insert a flat srewdriver in the back of the pan and carefully pry it lose. now trany fluid is going to pour out of the pan.
5. remove the rest of the bolts be carefull because the trany pan still has a lot of fluid in it.
6. grab ahold of the filter and pull it down.
7. insert the new filter but make sure the rubber gasket came offf with the old filter they have a tendency to stick in the transmission.
8 replace oil pan and torque down evenly
9 refill with correct fluid to the correct level
10 take for a drive and recheck the fluid level and check for transmission fluid leaks
ps when the pan is off clean the inside of it out with brake cleaner really good
If there are no leaks after you get done congratulate your self on a job well done
Service trans every 2 years or 24,000 miles.Buy a trans filter kit,remove trans oil pan,replace or clean filter(some tranys has a wire mesh screen in them that is cleaned,not replaced),replace oil pan & refill with recommended amount & proper type of fluid.REMEMBER THIS:CLEANLINESS IS GODLINESS WHEN WORKING ON AUTO TRANS,DON'T LEAVE ANY PIECES OF RAGS OR ANY OTHER MATERIAL INSIDE OF TRANS!!!
Have the vehicle scanned for diagnostic trouble codes,and repair any codes.More than likely the trans needs a rebuild.If the fluid smelled burnt,then obviously clutches or bands are burnt inside the trans.Changing the fluid just got rid of the smell,whatever is burnt is still hurnt.It is best to stop driving the vehicle,as continuing to drive it will just cause more damage to whatever is damaged.Those transmissions are prone to pump problems too.
