03mit lancer replaced tps shifts in 3 gears now no over drive

NOT TOLD WHY YOU ASK THIS?
IS THERE A PROBLEM NOT TOLD?
automatic transmission or manual where 5th gear is over-drive
?????
there are 3 automatic transmission, used.and told by you. or above 4th.
INVECS-II 4A/T (Intelligent & Innovative Vehicle Electronic Control System II)*
or
INVECS-III Sports Mode 6CVT (Intelligent & Innovative Vehicle
Electronic Control System III) CVT
OR
SST ,TWINCLUTCH AUTO
THE MANUAL SHOWS NO SUCH BUTTON.

Sanjay, the gear is slipping and needs to be checked by a good mechanic and fixed to avoid any danger.

you have blowen the transmission or the belts have snapped

well the tps has a big effect on shifting. if the tps is bad then the info to pcm will be off resulting in late shifting. good-luck!!

Before guessing at transmission problems, check the fluid level (car warmed up, engine running in Park on level ground) and have the PCM scanned for trouble codes FIRST.
Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.
Thank you for using fixya and keep us posted.

1. Extremely harsh shifts from P or N, normal shifts at WOT: EPC (Electronic Pressure Control) solenoid failed. Easy fix in pan. Fix as soon as possible or hard parts will eventually break.

There are two thing that may be happening that you have described, but you can tell which one it will be since your driving the Blazer. Both are simple to repaire, but to change the EPC. Your going to have to drop the transmission pan so that's going to be a transmission shop and call around, the EPC can be replace the same time there draining the transmission fluid when servicing the transmission which is about $110.00 for fluid and filter replacement and additional $65.00-$80.00 for the EPC valve.

Thank you for using Fixya and good luck. If it's the EPC failure, replace as soon as possible. may casue the sunshell to fractured or splines to sheared off.

Start with checking your TPS and if that is good then it could be your EPC (electronic pressure control) solenoid. Easy fix in the pan.

Thank you for using Fixya and good luck.

1-2 shift is delayed and harsh, may not shift into OD: Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.

Visit a transmission shop and have them put a line pressure gauge on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.500" boost valve (easy fix in pan).

Here is just a few things that are common to what you have described, I would start checking the Wire leads to the TPS and TPS it self. Good luck and keep me posted, be glad to know you got your Transmission running 100% again.

Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check Throttle Position Sensor (TPS) for smooth electrical response. If the response is jumpy or erratic at all, replace TPS. Good luck Auto Zone or Parts Source has this part and can be replaced with in 20 min. Both parts store will have the step by step instructions and i believe the cost is around $65.00 for the TPS which is better then a transmission replacement.

If there is an Auto Zone or any other large auto parts store, have them scan the truck for the DTC codes. The DTC codes will identify the Issues that needs to be addressed in your engine and transmission that has set off the service engine light on. Once the issues has been resolved, the light will reset it self after the third start up and after 40 start up will erase it self from the history as long as there is no additional issues.
