Ohh sorry to say your trans is going bad if not already gone..the reason it revs up " spiking "up but no move especially when hot is the clutches are slipping " worn out" and when the internal oil temp rises it gets thinner and more slippage and motor RPMS to provide more power..clutches are spinning and not holding...thus no forward movement...sorry for the bad news...Good luck..

SOURCE: See below

There are a few different causes that would give you that symptom. A worn Throttle position sensor (tps) would cause erratic revving, and also a stuck throttle cable/body as well. Take a quick look at the throttle body and move it by hand to watch the cable action, this will quickly tell you if it is the problem. The kickdown cable may be stuck too. The tps can be check with a voltmeter to see if it is within spec and adjusted accordingly. Any of these problems would be any easy/cheap fix for a mechanic if you cannot do it yourself. If everything checks out, then you may have a bad ECU.

Boy, do I feel for you...I hate to say it, but as a GM mechanic for thirty-five years, I can promise you that this 4L60E transmission is dead. Unfortunately, 4L60E's are relatively weak in stock configuration. I have repaired this exact problem many times. Here's what you do:
When you get the transmission rebuilt, tell the builder that you want, as a minimum over a stock rebuild, the following parts installled...you want a hardened input shaft, The Beast sun gear reaction shell, the 29-element Borg-Warner input sprag, the Alto master rebuild kit with all molded rubber pistons, all Alto Red Eagle frictions and full-thickness Kolene steels throughout (including in the low/reverse clutch pack--reverse is a weak spot for 4L60E's), 13-vane pump kit, the Sonnax .490" boost valve, a new reverse drum and an extra-wide (2 5/8") carbon fiber power band, a Sonnax cast-aluminum pinless forward accumulator piston, the Sonnax heavy-duty 2-3 shift valve, Sonnax "Super Hold" 1-2 and 3-4 servos, the Transgo valve body separator plate, and a 15,000lb-capacity auxilliary transmission fluid cooler, installed in series in addition to the transmission fluid cooler core built in to the radiator. This build will cost you about 600-800 bucks over a stock rebuild, but your transmission will shift firm, crisp, and reliably every time. You will think you have added about 100 horsepower to your engine without having even touched it. This transmission will tow anything you hook to it, will yank any Ford, Toyota Tundra or Nissan Titan all over the parking lot and burn up their transmission, and it will still be going strong when you sell the truck someday. GM trucks are awesome with the proper build on the transmission. I have three built this way, and tow a thirty-three foot camper and a 10,000lb car-hauler with all of them.

2002 ford escape red hot exhaust spudders and rpms drops to almost stall


Carol Ann,
Your catalytic converter is plugged up [restricted] This is causing the exhaust to get red hot and causing the reduction in power. You need to replace this part [$$$} The catalytic converter failed because you have been driving the car for months with the fuel mixture excessively rich.
You need to find and fix the cause of the rich mixture or your replacement catalytic converter will also fail in a few more months.

What are common symptoms of torque converter failure, and can a failing torque converter damage the transmission? Any answers are appreciated!


common torque converter failure symptoms are: higher than normal rpms at highway speed, rpm jumping in city traffic (press accelerator and rpms spike before you really start moving), lack of pick up, sometimes a loud roaring sound depending on type of converter. as far as damaging the transmission goes... not really, if the torque converter froze up completely then yes but that is extremely rare. the converter is probably worn out which is generally just letting the crankshaft slip before the transmission can get the power

2002 Ford Ranger transmission slipping?


The longer you drive with that condition, the more damage you will cause. Park it until you can repair it.

Think of it as how long would you think it is okay to run your engine without oil? Zero.
