Automatic transmission shift issues

If you get a chance try to grab a video showing the shifts. Typically slippage is either too low of fluid or failing clutch packs

 

My research says no slip yokes on Prerunners. It’s apparently just the tail end of the tranny. I’m not sure what to do with that… I’ll check the service manual.

 

Almost positive it’s the clutch packs. I’ll post a vid.

 

It’s at the differential side. Grease fitting on the shaft itself. My fathers 02 double cab prerunner has one.

not a slip yoke, just a slip joint that’s part of the shaft

 

Ahhh gotcha. Will check- hanging out in the bed rn Lol:

 

This it?

 

it'll be on the driveshaft. that right there in the photo is just a breather for the diff

 

look like this. the red cap on the photo is the grease fitting

 

Oh lol yeah I saw that when I did the u joints. I thought you meant ON the diff.

 

Thank you for imparting your knowledge- saved me lots of time and worry . Will still be checking on those clutch packs.

 

Old thread but adding if youve never greased that slip joint before, they take an abnormally large amount of grease to have them not make noise or move.. im talking when i tested mine i was able to make that joint move a little by hand. About 30 pumps of grease later it finally stiffened up and been good since.. but it aint like the half a pump you put in the cv joints before you pop a seal.. this youre filling up the whole section of the shaft.. kinda..

Also instead of popping the tranny pan off and only changing that fluid you should first change the filter and clean up the magnets and underbelly of the tranny guts and buy 4 extra quarts of fluid. Then fill the fluid you drained from the pan then with the truck warm and off take the transmission cooler line off and run them to a bucket preferably with marks of quarts on it. Then start the motor and dont let the bucket fill with more than 3 quarts before adding more fluid in through the dip stick tube.. keep doing the exchange till the fluid is all new coming out in the bucket.. this way you change the fluid in the entire system without disturbing the film on certain parts inside like youd do with a flush using solvents or flushing fluids..

 

Your solenoids in your transmission are gone. The 1st gen tacoma transmission soleniods have a bad reputation for going out around 250k miles. I had the same issue of my 2.7 4wd and I replaced them and my issue went away.
I think have the same transmission so that's probably what you should do.
The solenoids added up to about $200 but I also bought a filter while I was taking apart the transmission, which I would highly recommend.

 

This is actually bad advice. Filling the entire void in the slip joint is going to cause problems- it will feel like a jolt or axle wrap. Essentially the joint will be hyrdolocked in place and not be able to move. The real solution is to disconnect the drive shaft (make GOOD marks across the slip joint and shaft) and separate the two pieces, then apply an adequate coat of grease to the splines. If you have filled up the joint in the past, then take a long screw driver and remove as much of the grease as you can.
