Hydramatic auto trans will only move in low and reverse and slips bad do I need to replace trans
Not until you have done all the necessary checks. Check that the oil is bright cherry red and not tan. Have a pressure test done on the transmission to check for internal faults. Have the fault codes read to check for transmission faults (TCM ) check oil level. Remove the pan and clean out the filter./ If there is band and clutch pack linings in the filter then you may have to have the box overhauled.. If not adjust the bands and clutch packs . After all the checks are done then and only then should you consider a replacement transmission and only from accredited transmission shops

yep, sounds like your transmissions on its last leg, mabye you can get by, by starting in 2nd, if you have the option lol, but auto tran's are pretty cheap on ebay or try www.supraforums.com seen one for 300$

did you bleed the hydralic clutch system on this vehicle? = air in system or not bleed properly.
most of the flywheels for this model were not to be machined...... however it is ok to machine these only slightly but you must machine the surface the clutch plate contacts with the same amount as the outer raised section the pressure plate bolts to.
new flywheels have painted stamped writing saying do not machine...so if hydralic system is ok find out about flywheel.
also may pay to check clamping force of pressure plate most clutch places can do this or some workshops that is if fingers on pressure plate are all at the same height, not broken or cracked..

your check engine lamp is probably on because the vehicles computer is not receiving a vehicle speed signal, because your speedo is not working. You need to check the sensor on the gearbox and the head unit in the dash cluster. The gearbox sensor has three wires, one is power to the sensor and should read 12volts with ignition on (but engine off), a second wire is the earth for the sensor and should read 0volts and the third is the signal wire which can read anything from 5 to 12 volts. This signal should jump between zero volts and the signal voltage (5 to 12 volts) when the gearbox is rotated by turning a rear wheel (with the other wheels chocked to prevent the vehicle moving..and rotate the wheel by hand as some of these vehicles have a limited slip differential which can cause serious accidents if you try this with the engine turning the wheels...so don't). If the sensor is not getting 12 volts, check fuses and harness connections, if the signal voltage is missing check the head unit as this comes from the head unit to the sensor. If the signal voltage does not fluctuate when the wheels are rotated, or stays at zero volts, suspect the sensor.

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.
Secondly, put a line pressure gauge (or visit a local trans shop) 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).
Slow, slipping or no reverse: “lo-reverse” clutches are worn out, fluid leak in the reverse apply circuit, or broken sunshell. It is possible to remedy a fluid problem by removing the checkball from its cage in the case in the rear of the trans may help (must remove valvebody), or adding a high-viscosity additive such as Lucas Transmission additive or other seal restorer product. May also have worn boost valve (can replace in the pan).
Soft shifting, gradual performance degradation: Poor line pressure rise due to leaking boost valve, clogged EPC filter screen, failing EPC solenoid, or worst case: leaky seals throughout. Transgo HD2-C kit fixes first two without removing trans. Seal restorer may fix last problem, but probably R&R. Also try a transmission flush with BG brand products (Firestone stocks it).
No movement in any gear: pump failure, or total loss of fluid. R&R, or refill pan and find the leak. If out of fluid, avoid running the engine until the trans is refilled to avoid pump damage. To check for pump failure, check fluid level with the engine off, then start the engine and recheck fluid level. If level does not go down when engine is running, the pump is broken.
1-2 or 2-3 shift is slow/soft above part throttle: Trans is on its way out. R&R
Good luck and start with checking your transmission fluid level. Thank you for using Fixya

I currently have the same problem, and looking at replacing the transmission wire harness. I'm hoping this will cure my problem. My volkswagon mechanic thinks so anyways.
