Scania N113CRB luver SG The bus that's being thrashed sounds like one of the bus on 171, also being thrashed.
IndyB961E SG Good morning! I'm from the Czech Republic, the city of Ostrava. We are solving a similar "mystery" about different style of ZF shifting. I think it is the same problem. Both buses have ZF 4 HP 500. But I dont think it is caused by the driver (bus being driven lightly and a bus being thrashed is very obvious). The 1st sound is Karosa B741.1908 and the 2nd is Karosa B741.1922 or serviced 1908. http://screamteam.cz/upload/upload/4232.mp3 http://screamteam.cz/upload/upload/PRA%2024-91.mp3
Scania N113CRB luver SG The first one sounds like Scania ELBO! Regarding bus being "thrashed", try taking TIB1132D (180 JKDEP), it actually sounds like a CVT-ed bus. Cant really hear the usual ZF shifting. It actually has something to do with the drivetrain, like what IndyB961E has said, rather than being thrashed. TIB1132D is the most obvious.
Scania N113CRB luver SG Yes, but the second one is lock up at second gear leh, all L113s lock up at first gear. But it does sounds like Scania L113s! ( as in engine sound)
IndyB961E SG It might sounds like SCANIA, but i don't think that SCANIA has the LIAZ engine . You're right, the second sound (B741.1922) is locked up at second gear, but when is the first (B741.190 locked up?
Scania N113CRB luver SG It locks up at the first gear, you will feel it when then bus moves off on first gear then you get a slight "boost" and you will hear a "wheee........eeeoorr" sound.
IndyB961E SG I think I understand what you mean. So if I have ZF transmission, can I set when does the torque converter lock up? At the first gear or the at the second gear? Or it depends on speed or acceleration.
stooper SG Its already pre-set. The driver won't be able to change it no matter how hard he floors the accelerator.
The_Bus_Guide SG The driver can’t but the technician can. You can re-program the gearbox. Its all in the electronics.
IndyB961E SG Tahnks very much. In our forum some people still say: the typical sounds are caused by the engine or by the differential, but not by the gearbox . Is it true that ZF lasts about 3 years? And what other options can technician re-program?

TWS4793 SG Anyone have the timing on when the Service 66 CNG buses (SBS 2990E and SBS 2991C) will arrive at Block 139 at Bedok North Avenue 3 and at Bedok North Bus Interchange? I need all the timings of these buses because: 1. I had not boarded these buses before; and 2. I had not taken a proper picture of a CNG bus yet!
SBS351M SG aiya, Volvo where got good, the Causeway bus think MAN coach is best lah, can speed, not like Volvo, maybe gearbox they do something to the Volvo?
Scania N113CRB luver SG Who say Volvo cannot speed? Volvo cannot speed is because of the speed limiter....Otherwise Volvo is quite a good sprinter... Last time took a Volvo B10B coach at Thailand and its speed was rather good...Some people also said that the B7R is a good runner too. Volvo chassis i think is rather good and solid, with its TX platform...I believe Volvo chassis is one of the best?
SBS351M SG MAN can speed one, on expressway the MAN can overtake the 506 Volvo, should be the gearbox different one.
