Autozone's scanners don't translate GM manufacturer specific DTC error codes too well. I don't think you have 4 wheel drive in your Firebird.

If you are really having auto trans problems and its a bonifide odb-ii code as far as P1870 and triggering a SES light, it generally means Transmission Component Slipping. The PCM monitors torque convertor clutch (TCC) slip speed by calculating the difference bewteen engine speed and drive output. It's detecting excessive slip related to the torque convertor.

Possibilities are the torque convertor, valve body related such as stuck 1-2 or 3-4 upshift solenoids or the TCC regulator valve, burnt or damaged 2nd, 3rd or 4th clutch plates, etc.

Are you actually experiencing problems like erratic shifting, delayed shifts, up shifting only after letting off the gas or over-revving?

A common problem with the 4L60E tranny was the TCC regulator valve on the valve body. Sonnex has a TCC regulator valve kit that should correct the problem. Transgo has performance shift kits that will probably take care of the problem. On my son's '96 Trans Am we wound up putting in a Transgo kit and replacing the torque convertor with an aftermarket. He spent too much time at the dragstrip and sooner or later you got to pay the Piper.

Does that mean when you do a burn out that the smoke comes off the rear tires versus the front? lol.

Last time I checked a 4L60E tranny was for GM rear wheel drive only and I'm quite sure the guy that needs the help knows he's got rear wheel drive without insulting his intelligence.

hi guys,

first of all, thanks for your replies. sure l know that my car has rear wheel drive.. just firehawks are all wheel drive l guess, l read this somewhere on internet.. l just do not know so many things about engine.. also l cannot burn my car.. when l move immediately, l hit the accelerator all the way down, bu the car doesn't burd. it just moves real fast. it s automototic transmission.
by the way, formula LT1 l haven't checked fluied.
now l will go and check it..

thanks

Firehawk's or any other F-body's never left the assembly line with anything other than rear wheel drive. So where ever you read that. Never pay that site any attention again cause its full of crap and low fluid levels causes slipping so it could very well be a super easy fix. Good luck and let us know how it turns out.

hey bnaylor3400,

l am sorry l forgot to answer your question.. when my car changes gear, it is jumping to front.. l always hit my heas to my seat. especially from 1 gear to second gear.. ok my car is areal strong car but, it shouldn't be like that l guess.. l mean it is not changing the gears smoothly.. do you think that is normal for formula superchargers or something is wrong??

Thank you..

[BNaylor]

I'd go with FormulaLT1's suggestion first and then let us know.

hi FormulaLT1,

thank you very much for information about firehawk also.. l remembered now, it was on autotrader.com l saw it there. all wheel drive, blah blah.. anyway l just wanna solve my girls problem..

l juest bought it.. even l haven't payed the first bill yet.. and l drove it just 200 miles. ( l bought it 1 month ago)
by the way FormulaLT1 l just opened the hood, and l couldn't see fluid place for transmission, there is just one for brake. could you please let me know what should l do step by step so l can do it right away and let you know??

thank you

[doodad]

hi bnayloer3400,
l will do everybody's suggestions, because you guys knows everthing better than me.. and l tried to do it but l couldnt find the fluid place l am sorry..

[FormulaLT1]

The dipstick to the tranny should be passenger side rear of engine. Running along the firewall. With the vehicle level, start the car put it in each gear then leave running in park and pull the dipstick, wipe it off and then note the temp of the fluid and it will be marked cool/warm/hot on the stick and should be within that range within what temp it is. If it is below the cool mark it most definetly is low and that is whats most likely causing the slipping.

[doodad]

thank you formula LT1, now l will check it.. by th way, l have a cellphone with camera and l always take pics.. if you go to supercharger folder, you will see my engine pics.. l took them 10 mins ago.. and after l check that dipstick, l will take pic. again and you will see on the pic, what level it has.. l will be back soon.

thank you..
