"check transmission" LED on 4jg2 trooper bighorn

[t2erns]

actually i'm not familiar with your trans but i'm explaining some basic principles of a/t trans. if your trans is electronic you most probably need a scanner for it, since it's an isuzu maybe you can go to isuzu dealers and inquire if they can scan the trans or gm might able to scan it (tech 1 or tech2 scanner), gm used to carry the isuzu imports.

sorry for the very late reply, i kinda gave up na sa trooper namin until i saw this reply. i didn't know na may input and output sensors pala. i also noticed na you mentioned new A/Ts ours is old na 1996, i dunno if this solution will apply in our case. im still wondering how to fix this problem. i'm really losing hope, ilan years na ganito yung sasakyan namin.

Bro, sa tingin ko TPS ang problem or wag sana ECM na ng bighorn please check this link. http://tsikot.yehey.com/forums/showthread.php?t=40136

update lang guys, finally got the speedometer problem fixed. looks like it was the speed sensor nga, got one bnew for P2,200.00. haaay, now everything's back to normal na.

Reviving this thread.

Experienced the same problem today- flashing CHECK TRANS & SPEEDOMETER STOPPED WORKING. Other than that, truck seems to be running fine.

Hindi ma-diagnose ng mechanic ko yung problem (kasi computer & automatic mahirap daw), but based on this thread mukhang speed sensor kailangan ko palitan.

Several questions lang po:

1. Saan location ng speed sensor? Pag maturo ko sa mechanic, kami nalang magpapalit.

2. Sa pag-canvass ko may 2 klase daw: 1. may wire 2. walang wire. Ano dun ang sa 96 Bighorn 4JG2 A/T?

3. Sa presyo- may Korean made na 2200+ (Jetco).
- original 5200+ (Jayson's)
- original 7900+ (Casa)
Ok ba yung Korean made? I'm assuming yun ang nabili ni attic-dude. O pag ganyang pyesa dapat ba original?

Salamat at sorry sa maraming tanong.

Nag bblink din yung akin, sabi ng casa sa sensor daw pero wala pa silang stock so oorderin pa. Hindi ko muna inorder.
After a few days nag drive ako sa nlex, hirap na hirap yung makina pag dating sa 80 papuntang 100 km/hr, para bang naka overdrive lang lagi, tnry kong patayin at buksan yung overdrive (yung maliit na button sa kambyo), parang walang pag babago sa takbo. Nag init ulo ko kasi mukang mali yung diagnosis nila. Tama ba na ung "sensor" na sinasabi nila yung problema? And it will fix the shifting problem?

Namatay na din ba speedometer mo? If so, magkaka-problema ka talaga sa shifting kasi basis ng shifting ang speedometer.

nope, bago lang ang cluster meter ko. Everything on it is working fine except for the check trans.

all, i am new here, i got xwind xto 2001, i'd noticed that its hard to pick up speed from low gear, my engine rpm is too high already (2000-3000rpm) and one more problem is delayed shifting from 3rd to 4th gear and once shifted the rpm suddenly goes down to normal revs that was the first problem i'd noticed then lately after my radiator was overhauled i blew the tube for ATF of my radiator just by my curiosity and it seems like its is blocked i cant hardly blow it, please advice regarding this ATF line on my radiator maybe this is one reason that the oil pressure will drop as the ATF cant return normally to transmission once it goes to radiator to cool down and i got also check trans light blinking after running for few days after my radiatoir was overhauled.
FYI; my ATf was changed last Dec. 2010
