Terex Backhoe loaders

Manual transmission fluid capacity & service interval

Terex Backhoe loaders require manual transmission fluid with a capacity of 20 liters. Service intervals include checking at 50 hours and changing at 50 hours or 1000 hours. The data covers 7 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • All Terex backhoe loader models in these specifications share a uniform 20-liter transmission fluid capacity across every listed configuration. A capacity at this level is consistent with a full servo power synchro transmission fill rather than a partial top-up volume.
  • The TLB840PS covers model years 2010-2013 and carries only a normal use interval schedule, with fluid checks required at 50 hours and full fluid changes at 1000 hours.
  • The TLB890PM, TLB890PS, and TLB890SM each carry two separate service schedules: one for normal use and one for initial service. Under normal use, all three models specify a 50-hour check interval and a 1000-hour change interval.
  • The initial service condition for the TLB890PM, TLB890PS, and TLB890SM requires a transmission fluid change at just 50 hours. This early change interval is standard practice for new or rebuilt transmissions, as it removes metal particles and contaminants generated during the break-in period.
  • The 1000-hour change interval under normal use applies equally to all four models in these specifications. On construction equipment, hour-based intervals reflect operating time rather than calendar time, since machines can accumulate hours at highly variable rates depending on workload.
  • The 50-hour check interval under normal use does not involve a fluid change; it is an inspection point to verify fluid level and condition. A separate 50-hour change applies only under the initial service condition for the 2012-onward models.
  • The TLB840PS shares the same 20-liter capacity and 1000-hour change interval as the later TLB890-series models, despite covering an earlier and non-overlapping production period of 2010-2013.
