Just had a transmission replacement in an 06 nissan frontier (by nissan dealership). Now I feel a shudder when driving around 40-50 mph. My assumption is the torque converter is going bad or is bad.My question is did they swap out the torque converter with the transmission replacement? or am i still using my old one? If its a new or reman‘d one that came with the transmission does my 1 year warranty cover this?
No, the torque converter is not *necessarily* replaced when a transmission is replaced, but it often is. It depends on the cause of the failure and other factors, but it just makes sense to do so, given the high cost of labor, and the low cost of the part. However, what makes you assume that the converter is bad?? And was it truly a new transmission (unlikely, even at the dealer - probably factory recertified or some such)? Simply check your receipt for the work. If it has a torque converter listed under Parts then you can assume it was replaced. If not - and somehow your wild guess about the torque converter is correct - then NO, it would not be covered by a transmission warranty - either for the parts or labor to remove the transmission - again.
IT should be covered under the warranty and shame on them if they did not replace that while they were putting in a new tranny. Jasper transmissions come with a new torque converter.
if there were signs of particulate matter in the trans fluid, then a converter change would be warranted/manditory every time. converters have a low spot. and they turn. centrifigal force will trap most if not all particulate matter. can not be flushed with any degree of certanty. replcacement is manditory. if not replaced and new trans is installed, then the verter will re-contaminate the entire system. no particulate matter? verter change is not manditory. maybe suggested, but not manditory. that is iffin all outward symptoms do not point to a verter issue. no comment on warranty coverages. USAF tained hyd/pneu tech. old fart, common sense, and rebuilt my fair share of auto trans. to be fair, not one of these though. i would heeed our resident ASE Certified Mechanic. they're usually right.
