    Hello, I have 2000 E250 van that I put a new transmission in about 4 years ago. Worked perfectly until recently it doesn't shift to the lower gears. So it wants to start out in like 3rd or 4th gear. So it barely makes it from a stand still position and then starts working pretty good after getting up to like 30 m.p.h. Going up a hill or small incline at a lower speed. Barely makes it. It has a U on what type of transmission it is . It is a triton V8 5.8 l thanks for any help you can be. I appreciate it

    Hey Mark, I hope you can help guide me in the right direction. I just bought a 2005 F250 6.0l. The previous owner had the transmission rebuilt May 2013 using a Billit River City Diesel torque converter, billit input shaft and Suncoast Iropac-3 rebuild kit with transgo shift kit. This was only about 6,000 miles ago according to him. He had it tuned really high and was towing with it a bit. After bringing it home, under fairly hard acceleration, I get a buck or jerk almost like it misses the gear and then catches. This will happen in the 1-2 shift 2-3 and I believe 3-5. Any help what to look for?

    Hey Mark thanks for responding. Sorry I meant transmission range sensor. I replaced the rear speed sensor and throttle position sensor because it threw a P2106 code. I found out that, that code was thrown because of the vehicle's mph gauge spiking. I forgot to mention that the mph gauge shoots up to around 80-90 mph when the truck neutrals out. I thought that the sensors had something to do with the problem. And as far as the code reader, the one that was used is the same a repair shop would use. The ones where you insert keys into reader depending on the vehicle.

    Hi Mark, I hope I'm not out of line contacting you directly. The problem started about 3 weeks ago when my son was at a red light and the truck (04 Explorer 4.0, 4x4, auto, 130,000 mi.) would not accelerate when the light changed. I replaced the rear speed sensor, and throttle position sensor. Following day he was on his way to work and the vehicle neutraled out going about 40 mph. Only way to get vehicle to move was in 4L. Unbolted shift motor, left electrical connection together. Drove truck for 45 mins with no issues, shut down and restarted. Big mistake... the truck would not engage in any gear but 3rd. Changed tranny fluid and filter. Also tried to replace TSS but was unable to remove nut that holds manual shift lever. Spent 5 hours on that nut....will not budge. Reconnected shift cable and shift motor. Truck will not engage in any gear including 4H and 4L. Buddy of mine scanned truck. Scanner read "Electric Clutch Relay Circuit not responding ". I'm LOST.. Can you pls help? hdel

    hi mark . sorry to bother you, but i have a quick question. i have just bought a 2002 mazda b3000 (ford ranger) i have the dreaded p0720 code for output speed sensor circuit. the tranny will drive in 2nd manual, and is slipping in reverse, and thats all it has for action. the last owner said the speedo started reading 140 mph even though he wasnt doing that speed. the tranny 5r55e was rebuilt june last year(14) but the shop that did the rebuild will not honour the warranty because of change of ownership.
    have you ever seen the output circuit cause similar problems, or do you think im barking up the wrong tree. i am presuming that everything should be good in the tranny, and was wondering if this circuit failure would effect the shift solenoids ect. sorry for the long winded mail, but i would really value you opinion.thanks. all the best for 2015. steve.

    You should look at gear ratio to see if the measured ratio in second gear is correct. That's my only suggestion right now.

    I should mention also that this is the ONLY code I can find, with the Ford diagnostic tool I'm using. I was under the truck inspecting other things when doing brakes, and find it to be almost impossible that I bumped the OSS or any other sensor on the trans. Just seems like a coincidence I suppose. Only thing done to the truck is 285/70/17 tires...

    Hey Mark, I've seen your posts on here and think you may be able to help me. Out of nowhere, after doing my brakes the other day, I'm getting a p0732 and "trans fault" on the dash. I know that this is a 2nd gear ratio code. Literally the truck has never been off road, etc. and was not even being driven the day this came up. it's a 2005 XLT Supercrew with 179k miles. Trans shifts like garbage, basically slipping thru 2nd, to 3rd it seems like. This all happened in one day, all at once, ironically-after doing brakes. I have access to IDS from work if that helps, but am no transmission expert. Trans fluid level is fine, doesn't smell burnt. Truck is a 2005 f-150 XLT Supercrew with 5.4/4r75. Thank you in advance for any help.
