Check the operation of the TCM as it may not be sensing the selector position correctly. Check the selector position on the box as it may have slipped and not selecting the forward gears because it is out of adjustment.

My 92 dodge caravan won't go in any forward gear but park,reverse and neutral warm fine


If engine RPM goes up when you try to go forward but vehicle won't move the forward gears is not engaging in transmission. Could be caused by several things. Check transmission fluid both level and condition mostly condition. Get a white paper towel whip dipstick on paper towel and look for any gray in fluid if transmission fluid is gray you have metal shavings in fluid. Most likely need a new or rebuilt transmission.

My daughter has a 92 ford tempo 2.3L automatic that suddenly has no forward or reverse gears. Fluid level is high despite not adding any fluid. Any ideas?


Blocked transmission fluid not circulation through system could be a clogged filter. Might have burned out transmission. Check fluid for a burnt smell and a greyish color to check color whip dipstick on a white paper towel. If grey that is metal shavings and transmission is heavy damage inside

I have a 6.5l diesel gmc the trany works fine in forward but not in Reverse


Check the fluid level with the motor running and at running temp. Level and if there are metal shavings. If level is good and no shavings then may just need a tranny flush.

96 nissan sentra 5th gear grind


Mor than likely damaged one of the planetary gear sets. Grinding in a trnasmission or rear end is a sign of loss of contact between meshing gears. Automatic transmissions engage two sets of gears internal to the trans to create a forward drive gear, changing between the gear sets creates different ratios anwhich in turn aloows for higher speeds. If the trans only grinds when in fifth range there is mopre than likely internal damage to the gears which 5th needs to operate. I would start by pulling the dip stick for the ****** and check for black or shiney material on the stick. I would then take a sample of oil from the trans by draining some from the drain plug if it has one, or possible drop the pan and check for foriegn matter in the fluid. Peices of metal shaving point to gear damage, and black material pont towards clutch wear/ damage. A worn or damaged clutch will cuase that specific gear not to engage and cause a grinding noise. Either way the concern is internal

Tranny trouble??


TRANSMISSION FLUIDS CAN BE CAUSED BY ONLY A COUPLE OF THINGS. MOST COMMON BEING A WORN OR BROKEN SEAL. THE TRANSMISSION SEALS ON MOST CARS ARE MADE FROM RUBBER OR METAL. BEING IN ALL KIND OF EXTREME TEMPS FOR YEARS ON END NOT TO MENTION THE PARTS MOVING AROUND THEM WILL EVENTUALLY CAUSE LEAKS. ALSO FAULTY INSTALLATION (OF A SEAL) CAN ALSO CAUSE A LEAK TO HAPPEN. THE ONLY OTHER THING THAT CAN CAUSE A LEAK TO MY KNOWLEGE WOULD BE IF YOU BOTTOMED OUT A CAR LOW ENOUGH THAT IT CAUSES DAMAGE TO THE TRANS CASE OR PAN. One cause of grinding when shifting into reverse is improper adjustment of the clutch linkage. If the adjustment is correct when the clutch is depressed the gears should stop turning and eliminate the grinding. Make sure there is some free play in the linkage when the clutch is not depressed. Most manual transmissions do not have a sychronized reverse gear. When you try to go into reverse from neutral, the transmission countershaft (which is linked to the pilot shaft) is still turning. The main shaft (which is linked to the tailshaft) is not turning. Therefore, since there is no sychronizer (or clutch brake like on a heavy truck tranny) the sliding cluctch gear (splined to the main shaft) grinds against the main shaft gear (floating over the main shaft but meshing its respecive countershaft gear through the reverse idler). The slider's function is to lock the main shaft gear to the main shaft thereby transmitting power to the rear wheels in the desired gear ratio (depending on which main shaft gear is locked to the main shaft). The way to cure this is to select a forward gear to stop the transmission and then go to reverse, all the while holding the clutch down. If it still won't go into gear you can either slip the clutch ever so slightly to "bump" the gears while gently pushing the stick into reverse (not too hard!! you can bend or break forks!! OUCH!!) or go into neutral, let the clutch all the way out, go into a forward gear and then reverse.

Transmission wont shift into reverse


By the grayish color, fluid being thick, and metal shavings, the clutches are pretty much worn out. It's time to either rebuilding your transmission or just installing a good used one. The fluid normally should be a reddish color. The gray is from the actual clutch material going away.
