If you have no reverse then yes it needs to be rebuilt. as far as the whining it could be in one of the differentials. or in trans? just depends on where you hear it

Check your fluid level to make sure its up to the specified level, then I'd be checking out your linkage from your shifter inside the car right to the transmission, it sounds like to me your linkage may be worn enough to put the vehicle in drive but not reverse. The linkage bushings are a common problem on vdubs. See if you can put the car in reverse by moving the linkage arm directly attached to the transmission (make sure you have someone in the car with the brakes on or caulk the wheels) if it does go into reverse when you manually move the direct linkage arm at the transmission then replace your linkage bushings, if not then the only other problem would be a transmission internal problem. Good luck

I would begin by replacing the filter if its not new, 2 possibility of issue, faulty shifting module or defective transmission rebuilt. just because it has been rebuilt does not mean the individual work on it did a good job. the less cost effective way is to locate used modulator from ebay or junk yard, if that does not rectified the issue than more likely it will be the tranny. the bad part is that I dont know of a company offer a bench test for the tranny modulator.

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
