Transmission Shifting Problems & Non Working Speedo/Odometer
I have a 94 F150 2wd 5.8 V8 w/ I believe is a E4OD Automatic Transmission. 180,00+ miles. It started to shift pretty hard in every gear once in a while but now can do it all of the time. I'm scared I'm going to do some damage to something so when it gets to a certain RPM, I ease off the throttle and let it go into the next gear and then I start back on the gas. It also downshifts pretty hard too. When I say it shifts hard, it's like BAM then it's runs fine. When this started, I checked the fluid and it might have been right on the line but not really low. I added about a 1/4 of a quart, (is that a real measurement? lol), but still drove the same. The fluid was red, like it's supposed to be, not burnt or anything, just the same as new fluid. Anyway, now after this has happened, I have lost my speedometer and odometer, they just don't work now. I was wondering if this is all related? When it shifts from 1st to second, I think, maybe 2nd to 3rd, it BAM, goes into that gear and it seems to shift normally into another gear right after that. Even going into OD, it shifts hard. I'm not even close to being hard on my vehicles but I don't baby them all of the time. I've done a lot of searching on this forum and one thread says it could be the Transmission Range Sensor. My mechanic and I have talked briefly about it and he thinks it's electronically related. I'm stumped. I was having somewhat of a fuel pump related issue but I drive it locally so that's the least of my worries. I love my truck but with all these issues, it would be cheaper just to shoot it that try to figure and solve all the issues with this truck. If I can just get the transmission problem solved, I'd be a happy camper for now. I hope I gave enough information to solve my problem. Thanks for any and all help.
BTW, this tranny shifting problem happens about 95%+of the time. Sometimes it shifts like normal.
