trans am going out or etc

[FMR_TransAm]

my car had a TPS engine code, since i fix it the car on WOT gets to 5k around then revs to 6500 and still goes back to 5k then 6500. rpm and the car is still moving? is this my transmission going out. i have a 4L60E

How many miles on it?


It could be the torque converter is starting to slip.

^ This. Now that your engine is at full operating capacity, your trans may be too weak for the engine's power output. Since you have an automatic, when was the last time you had a drain/fill or trans flush? Have you ever replaced the trans filter? Just something to start looking into.

[FMR_TransAm]

i drain the trans fuild during the cam swap about 1 month ago.

Did you add the appropriate amount back in? Checked the fluid level while the car was running?

[SMWS6TA]

you said you change the fluid but did you change the filter too?

[pajeff02]

I must be seeing double...

This,,, and did you add enough fluid, then check it while the engine is running and trany hot?

The 4l60e is very particular about it's fluid level.

talking to friends and looking at it, the Engine Codes that on are P0121, & P0122. the the Idle is high, on shifting from 1st to 2nd its going up to 3500rpm to shift. WTF. NO LEAKS OR ANYTHING. can someone help me

[cammed goat]

I just looked up those codes. They are throttle position sensor related. The PCM is probably going crazy trying to keep the air/fuel mixture even in order to keep the engine running.

[FMR_TransAm]

its surging badly and from 1st to 2nd gear its going to 3500rpm, the TPS is a pain to fix. plus im getting 11mpg cause of it

[SMWS6TA]

TPS is just 2 bolts on the TB cost about $60.


You seem to have 2 different problems here.

[FMR_TransAm]

i already brought one, a TPS Sensor and its still acting crazy

[SMWS6TA]

Without seeing the car in front of me it's kinda hard to help.


ok, let's start fresh. Here is what I understand is happening now.


@ idle it surges up high.
While in gear it revs to 3500-5000 before it shifts.
You're getting codes for the TPS, but you already swapped it out and are still having problems.


1st - Have you gone over and checked to ensure all of the wire harness are connected?


2nd - this may or may not be a help but...


Do me a favor - check your voltage gauge. Is it below 13 volts?

Next check the alternator - is it covers in power steering fluid?


I ask these because when my PS pump leaked onto my alternator it caused it to go into "limp" mode. The PCM surged the motor to 3500-4500 rpms trying to trip the alternator to charge the battery. I had to use another battery to get it home. Once I swapped the new alternator all my problems went away.


If you check this it will help in eliminating a possible problem.

I think it has already been posted somewhere but "new parts" do not always equal "good parts". They can also fail shortly after installation or not work right out of the box.

Do me a favor - check your voltage gauge. Is it below 13 volts? The Volts is around 10 - 13 on idle

Next check the alternator - is it covers in power steering fluid? Havn't check it, but will Firday Morning.

the volts you posted are slightly low. Should be charging around 14-16 volts depending on what cycle it is in.


I'll wait on the answers form the other questions.

[FMR_TransAm]

When thr key is in the ON position thr volts is 10 in the yellow on idle is about 12-13 im looking at it but cant see anything yet

[SMWS6TA]

one more thing there is a small thin single wire that connects to the top of the alternator. Make sure that is connected.
