Thanks a lot for you support. Insya Allah I will share more video for troubleshooting CAT Machine.

Hi, Ganesh. Sorry for delay response. If intermittent problem(electrical), you should have some logged diagnostic codes. Give me codes and I can advise you.

That's sticker applicable for 140H also. 140K only different design of mounting solenoid to transmission CV. Is it only 1st gear not shifting? Or all gear? Give more details of the issue so that I can advise you. Thx bro already support my channel.

@@arymancat7064 customer said that it will stay in first and not come out first forward. I checked the resistance on all solenoids and all but one solenoid was within specification which I believe 30 ohms +- 3 ohms. The bad solenoid only had 18 ohms. I ordered it on Friday and won't receive till Monday but if that doesn't work I fear it will be a harness issue. What ecm gives power to the solenoid? And where is it located on 140H?

In first gear there are 3 clutches engaged. First forward (1F) 1 - 6 - 7 and 1reverse 3 - 6 - 7. If operator not complaint for reverse, we can skip clutch no. 3 (direction clutch for reverse). If clucth no. 1 has problem, it should effects to other gears (1F,4F,5F,7F, and 8F. If clutch no. 6 has problem, it's should effects gears 1F, 5F, 1R, and 4R. If clutch no. 7 has problem., it will effect to gear 1till 4 forward and 1 till 3 reverse. Output voltage from ECM to solenoid are 24 VDC. Chassis ECM is located in RH downside of cabin. Thx Bro for comments.

@@arymancat7064this channel is the only channel of its kind so please keep it up and I guarantee it will be successful. Keep the videos coming!! Take care my friend! Cheers from NC machinery CAT in Alaska!

@Uriel Cisneros, thanks for support Bro. Please share with your friends if you are happy for this channel. Thx a lot.

Hi, Biniam, what do you mean all power is good. Electrical power supply? Engine horse power?. Any electrical warning on monitor (like transmission symbol blinking)?.

OK. Thanks brother.

Hi, Samuel. Thanks for watching my video. Sorry delay to replay you question. Fourth gear to 8th gear is controlled by clutch no.8. I believe gear will not shifting 5th Forward till 8th forward and 4th reverse till 6th reverse. Please check clutch pressure no.8 pressure (port D) (387 +/- 14 psi) - neutral. If 0 psi, make sure power to Solenoid no 8 available. Make sure no any active codes related with shifter gear switch and clutches solenoids. If all confirm no any electrical issue, you will confirm that shifting issue related with internally leakage inside clutch no.8 piston seal. If you found clutch pressure within spec or below but still no any response from clutch no.8. Easy way remove transmission screen which located RH of transmission (triangle cover with 1/2'' spanner). Remove and inspect the screen, if found clutch materials, the decision to recondition the transmission.

Hi, bro. I can advise only specific troubleshooting, so I can support you to solve the issue.
