What vehicle parts match 94 firebird


All depends on what parts you are looking for, the Firebird and the Camaro share the same platform so motor, trans, suspention are pretty much the same.

I have two toyota pickup truck 89 and 94 with 22re engine, I swap the engine the 94 manual transmission is ok but the 89 automatic transmission is not shifting into 3rd gear and the check engine comes


welcome to modern cars, the newer cars have a TCM.
you can just swap a mech, trans for a electronically swifted trans.
I swapped, you meant.
its not clear what you are doing here,.
why are you swapping engines
and are you expecting both cars to run? which makes above line odd.
no?

Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.

Trans shifts into gear harshly, car feels sluggish off the line
, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Good luck and get back to me, hope this helps.

As long as the transmission tail shafts are the same it should fit nice . check the tail shaft (not drive shaft) they are interchangable if it is longer or shorter.

a np241 from a th400/4l80e would have the 32 spline that is need for a manual trans, one from a 700r4/4l60e is 27 spline input, in 94 the switch was changed and the cam to activate the switch was changed so if you get a 94 np241 you then will need to wire in a 94 switch into the older harness

Will a 4L60e auto. trans. from a 1999 firebird fit my 94 camero z


the problem you will have is the trans for the v6 will have less friction material in it so it will havea very short life in a v8 car.. so no its not the same trans internally but as for the fit if the v6 is a 4.3 yes a direct fit for the v8 ..

Transmission shifts hard


Your car has the 125c/3T40 model trans,3 speed automatic with lockup.When you say you unplugged the "speedometer",if you are referring to a square electrical connector on the trans,facing the radiator,that connector is not the speedometer,but the lockup circuit inside the transmission.It is likely the lockup solenoid inside the side pan has gone bad and is malfunctioning.It is a common problem on those transmissions.You will lose some gas mileage by unhooking the connector,and eventually,years down the road,will hurt the trans from the fluid running too hot.Lockup clutch application in a General Motors lockup torque convertor helps to cool the fluid.
