Automatic transmission will not change gears, stuck in first

I bought this car from a salvage lot, it has 88,000 miles, the tranny was slipping, so i had it replaced, however the car will not move beyond first gear. The seller of the tranmission swears that the transmission was tested and works properly, the machanic swears he did a great job, however i am still having issues . Please help. i am considering changing transmission modules, and checking fuses where should i start, i can not afford another transmission

SOURCE: Engine missing Have to change sparkplugs every

First replace oil and filter in the transmisson next replace the spark plug wires and coat both ends of the wire with dielectric greese this should eliminate your problems. Also do a top engine clan to get rid of carbon build up and clean te throtle plate front side and back plus the port hole the plate is located in. Whith the throttle plate not fully closed it allows unburnt fuel to be depostied on the plate and causes it to run poorly.

SOURCE: Slipping transmission.

The friction plates maybe well worn and need replaced. Torque converter may be failing. Automatic transmissions can and will wear out in time. 14 years is alot for any vehicle.

SOURCE: transmision overdrive light started blinking check

Without the information as to why you had the Tranny rebuilt at 51K, I can share with you most likely the problem as per my experience with these units. The Valve body or Block depending on the year is going to be the accused problem as well as repair. Yet the reason most fail is actually the Servo inside the Trans Case itself.
Some common complaints associated with a 5R55S / 5R55W are high TCC slip RPMs under increasing loads, slip codes, and converter apply or release concerns. These complaints are often caused by wear at the ID of the TCC modulator plunger valve sleeve, due to constant oscillation by the pulse width modulated TCC solenoid. This plunger valve positions the TCC modulator valve, which feeds line to the apply circuit, which controls slip rate. Wear of the sleeve will allow the TCC slip rate to continue to rise, and could prevent full lockup.
The Servo kit assemblie restores hydraulic integrity to the TCC solenoid circuit with precisely tolerance parts. The elevated modulated pressure, will not raise apply pressure to the point of TCC piston fatigue, and will result in firmer TCC apply and reduced slip RPM in heavier use applications.
02 Explorers built prior to 03/04/02 with a 5R55W Tranny; can show no 3rd Gear, or slippage in 2-3 gear, with diagnostic codes P0733 & PO745 present.This may be due to a broken Band. Two tests will easily confirm or deny this problem.

Most assuridly the valve body or block will need to be replaced. But further investigation as to why should be a concern or the Valve Body or Block will be no more than a band aid. Repeating itself within a few months. Improper dianosis for these units are why so many Ford Owners are constantly bad mouthing explorers in the Forums.

SOURCE: the button on the automatic

The problem is the park safety switch on the brake pedal (a gblue rubber looking ring under u pedal) because it is not working correctly the pin under the center console is stuck and not releasing the shift
In my case the tip of the blue rubber ring under the pedal broke therefore it did not press the switch which pulls back the pin which locks the shifter in park. (this can cause your break lights to stay on if it breaks or falls off when you apply the brakes)
so, for a few dollars you can replace the ring which notifies the switch to allow the pin that locks the shifter in park to release it.
I did not know I had broke the blue thing (another day, another story) and needed to get somewhere fast so...
I removed the 4 screws that hold the face plate that the shifter sticks up through, I found a white pin down in the console (there is a square white switch underneath and to the left that works the pin, i bent back the bracket until i could pull the pin put of the shifter lock and put the car in gear. However, my car does not lock in Park now. I figure I could use the parking brake if worried which never have and i have had no problems. In fact I forgot all about it until reading this post. Guess I ought to put the pin back in the switch since a few weeks later I had to fix the blue piece in order to get my brake lights to turn off.. (the other day, the other story.)( and how I stumbled upon The Rest of the Story!)
I apologize for my undeveloped vehicular parts terminology. I am not of the male gender and therefore lack the DNA required for innate understanding of anything mechanical. But i can use a screwdriver and look around .....Its that easy!

Slow pick-up, high rpm

It seems as though the Transmission clutches are slipping if it's an automatic or the clutch is worn if it's a standard. If it's an automatic transmission check the Transmission oil it should be clean and no burnt smell. You will easily recognize burnt oil by it's nasty smell.

Transmission Slippage

You can have the clutch and the pressure plate checked. If it is an automatic tranny you may try to drain the fluid and have it replaced or have the solenoid cleaned out or checked. The solenoid controls the hydraulic pressure to the clutch

Slips between gears.

well I guess I will say change the fluid again and change the filter- you simply do not have enough miles to be transmission failure- so my guess wil be the shift solenoid as well - contact dealer to confirm.They will have to change with solenoid anyway.I sold my last honda with 275,000 miles and it had a hard life- no issues ever

Yes it does matter. Remember your filter is a screen that the oil flows over. If it is clogged it will not allow clean oil past it and to some extent will be like you are low on oil or high if the oil can not flow.
Change the filter and look for metal deposits in both the fluid and the filter. Minute shavings like sand or smaller is normal as long as there is not a lot. If you see a lot or see big particles then gears have been ground and you are looking at trouble. Get fixed early. Otherwise if filter is clean and fluid is fine and tranny still does this they make additives for tranny's to help with slipping. I use tranny medic. Follow the directions as you will need to drain some of the fluid out. Also do not add to your tranny unless you have met or exceeded the mileage specs on the bottle of the tranny medic. Hope this helped.

2002 vw jetta tdi - problem with rpm gauge?

Hi, Did you notice the motor actually reving higher when the tachometer was reading a higher rpm.. If it was it could be your transmission slipping.. Set your cruise control and listen to your motor while the tachometer starts moving erratically.. Good Luck
