Question about Dewalt Drills

DW988 1st and 2nd gear doesnt work, 3rd gear works

Ok, this drill has seen many jobs and has worked. I have personally replaced the trigger and brushings all within the past 1.5 years. after the trigger was changed the gears worked fine, then they started slipping, now i cannot get any torque out of 1st or second gear, they simply will not turn the chuck when any type of pressure is applied. I'm just curious as to if i need a new transmission assy or i may have reassambled it improperly when i changed the trigger.

when the trigger was changed had someone with me and they thought the chuck seized up and took apart the transmission assy. it was cleaned and put back together, and when the new trigger came in the drill worked.

any input would be helpful

You may have put it back together wrong, but you may also need a new transmission. 99% of the power tools I work on where the gears are slipping is caused by the transmission or gear box (both names are used interchangeably).
Good luck to you!

What is causing transmission to only work in 2nd and 3rd and reverse.? in 2nd and 3rd it feels like its trying to downshift into 1st. In 1st there is a little resistance but it doesnt move


How does your transmission fluid look and smell? If it is dark and smells a little burnt, the transmission is very likely toast. If it is still clear and red, you should let a transmission specialist diagnose it.

Hi. Just a long shot.
Might be an idea to take off the gearbox end cover
and check the mainshaft end nut hasn't worked itself loose.
I've seen this happen a few times.

TRANSMISSION


Fuse # 20 or 21 gets power through ignition. This fuse controls PRNDL indicator, speedometer, tach, & will cause transmission to not shift gears correctly. Ours took off in 3rd gear when put in Overdrive & only ran in 3rd gear. If we tried to manually shift thru gears (auto trans), it had 1st, 3rd, reverse. No 2nd or over drive. Replaced ignition. Fixed problem. Root problem was Electric motor that engaged 4 wheel low side was bad. Every time we used 4 Low side it threw power surge through ignition & blew ignition out. Good Luck.

The drive and 3rd gear do not work. reverse, 2nd and 1st work what is the problem???


Sound like you got a manual shifter problem.Either the linkage doesnt line up any more or the inernal bushing isnt allow the gear to line up.This result in being out of range to the target gear and it doesnt allow to go in .Then there are the binding of the gear selecting . That can wear out also , like the bushing, the linkages,

1989 jeep cherokee 6cly auto trans shifts great after gets hot 10-15 min. but when cold shift very high 4500 rpms 1st-2nd and wont shift to 3rd almost like stuck in passing gear. when hot shifts great no...


Sometimes you tranny may just be low in which case add fluid. Be sure to check while engine is hot, most likely in park or nuetral. It will say on dipstick. Also if you havent changed the filter you may want to do that, sometimes crud gets built up and it will not circulate well unless hot. If you change the filter, be careful as usually there is not a drain plug and the only way is to drop the pan. If you do go that route I advise buying a drain plug and drill a hole in pan and replace with plug so in the future theres less mess and a whole lot easier job. Hope this helps. Be sure to read directions on drilling hole for plug and be sure its drilled somewhere on the pan that doesnt get in the way of anything underneath.

Manual gearbox query


hi fro uk this is a common problem on many cars not just hyundai and ita most common cause of synchro mesh failure on2nd and 3rd gear is believe or not a bad driving habit! it goes like this when you set off in 1st then cange up 2nd gear whilst accellerating holding gearstick? in back position then change up 3rd gear still holding gearstick! in a forward position then? when up to 4th gear we let go of gearstick?? now just by holding g/stick whilst in 2nd and 3rd the slightest pressure also brings the synchro ring into play whilst gear already selected! so inevitably the synchro ring wears away to extent that they no longer work properly so the gearbox is none synchromesh on 2nd 3rd gears and on occasions? on 5 speed box 4th gear can become a victim ? hope you understand ? just quietly observe some peoples habits with manual boxes? as for repairs?cost? this is not a difficult job to replace all synchro rings but box has to be stripped and assesed ? the cost could escalate? but if you want quick turnround? a matter of hours? a recon box with warranty? is other option ? BUT would not advise risking a 2nd hand box probably worse or same as ? whichever choice you take you can check clutch at same time if milage is high? now some good advice! personally this is not a dire problem just a niggleproblem which if you take time in changing gears you can o/come gritty gear change save money for now till it is more affordable ? if you know any old timers truck drivers ? these are the guys who will show you how to drive /change gears none synchro mesh before it was ever invented ? hope this helps daughter but practice on gears and rid of the bad driving habit so many do not realise they have will make her a better experienced!driver
