Hi all, I'd like to start fixing up my old F150, hoping I could get some advice. I have a 94 with the 5.0/4R70W 2WD, ~108,000 miles. The transmission is starting to slip bad on the interstate and even around town some, seems to occur more on longer drives (when it warms up?).
So, I've decided to replace it with one from a junkyard with a 90 day warranty. I picked up a 4R70W out of a 95 F150 with the exact same setup, and am hoping to swap it out this weekend. The junkyard said the transmission was inspected by AAMCO, so I'm hoping all is well.
My questions is, would you have any advice, tips or tricks for the install?
I also need to replace the engine rear main seal, it seems to be leaking just a bit. I'm open to replacing anything else that is recommended, maybe the transmission seals or u-joints?
I've done a bunch of searching on this site and noted the following instructions for yanking it out:
1. Disconnect Battery
2. Remove Transmission Dipstick
3. Remove Inspection Plate, 2 Rubber Plugs (Bellhousing & opposite side of starter)
4. Remove Torque Converter bolts (4) w/18mm socket (turning clockwise)
5. Remove Starter
6. Drain Fluid from Pan
7. Drop any necessary exhaust (first unplug o2 sensors)
8. Remove Driveshaft
9. Support Transmission, Remove Crossmember
10. Disconnect all Electricals and Shift Linkage
11. Lower Tail End of Transmission – Remove 7 13mm head bolts
12. Remove Transmission
For these instructions, I wasn't 100% sure if it was for the 4R70W.
I've also read how to check the torque converter with a straight-edge, it seems this was already installed but good to check.
To note, I'm going to have a friend helping and have a motorcycle jack to hopefully support the transmission.
Lastly, I found what seemed to be good instructions for filling it back up:
There is no need to fill the converter. The pump will do that as soon as the engine starts to turn.
After installing the trans pour 6 quarts down the dipstick tube. Start the engine and run for 1 minute. Shut it down and add 3 more quarts. Restart it, and move the shifter to each position (PRND21) for 5 seconds each. With the shifter back in park let it warm up for about 5-10 minutes. This will also allow fluid to drain out of the dipstick tube so that you have a chance of getting a good reading. Check the level with the trans warmed up and the engine idling in park. Depending on how much was in the trans it will take 1 to 30 more quarts of fluid to top it off. DO NOT OVERFILL!
Sorry for such a long post
Any other advice would be extremely appreciated. Thanks in advance.
