How to install a shift solenoid?

I installed an electric fan=wired to a red wire that was hot only when key was on, wire was under hood near hinge on drivers side. Truck ran great for 10 miles. Next time I went to start it= would not start=blew fuse #18, fuel pump. Replaced fuse and truck ran great but when put into drive, truck shook, stumbled and nearly died. Thru codes PO755 = shift solenoid B malfunction and PO443= purge control valve malfunction. Disconnected fan and battery for half hour but still had the same results.

My automatic transmission (4R70W) is not shifting properly. The diagnostic code says "Faulty Shift Solenoid B". I do most of my own engine repairs, but not tranny stuff. I'm going to replace the filter. Can I get to this solenoid easily if I drop the transmission pan?

I've been looking online everywhere and can't find out how to change the shift the solenoid for my 98 f150. It's an automatic 4x4. Can anyone help me out?

I can not find the location of the speed sensor that controls the speedometer. Can you please help?

I have a 92 ford f150 5.8L when I drive my truck the speedometer wont work nor will it change gears, now when I drive it for a while it automatlay changes the gears and starts working fine. Could this be the VSS thats making this do this?/

Thanks for the answer. I was wondering how do I take out the VSS on the speedometer head. Is it by the trany

Your rite I should bring it in. I dont want to miss up the VSS or take something that I dont know. Were should I take it at?

1997 ford F-150 Standard with the 4.2L v6 and 4x4 automatic with the 2 or 4wd stick on the floor. 150K miles.
I had a bad transmission and bought a new used 4x4 auto and replaced it, all finished and started the truck, fixed !! Not quite, service engine light on and when I drove it around the block it hit hard going into 2nd gear other than that it ran and shifted OK only if I pampered it and helped it shift with the gas pedal. Took it to Advanced for a code scan and the guy (Meter) said "speed sensor malfunctioning !!". Went home ramped it and took the speed sensor out and brought it to the store and got a new one and put it in and reconnected the batt cable started it and Viola!! No light, drove it around fine and parked it. Couple hours and a shower later jumped in to run up to the store(Beer), Light was on and doing the same thing.

Here is the question, the old transmission has a diff. looking sensor (no gear on the end, just a snub end w/a little silver spot in the middle of the tip)

Is that the sensor I need to put in the new trans. to work with THIS transmission ? Also, the NEW sensor was not an exact match either because it had a female end next to the plug end w/an orange ring around it

and the one I replaced looked almost exact accept it had like a white cap or cover in the female end next to the plughttp://www.2carpros.com/forum/automotive_pictures/88237_498103_1.jpg" alt=" http://www.2carpros.com/forum/automotive_pictures/88237_498103_1.jpg" />

The white one here is the one that I took out and brought to the store to replace. Did I get the wrong one and it shorted out or should I put in the one from the replaced transmission ? Please help as I am very excited that this is the last step I am sure.... Also the speedometer works fine but the Odometr turns slow, It did that before th other tranny went bad though and I am pretty sure that that is is in the odometer itself.

Jesus christ, how much info and pictures and Money do I have to give you guys to get a better answer than that. Maybe if you said "Replace it with the same one you took out" I might feel better about the $60 donation !
