Am new to the forum, so firstly.. good day to you all and hope to be spending some more time here.
I've got an E36 325i Automatic (1993 model). The auto gearbox is giving me some problems but i haven't got a clue what could be causing the problem.
It is only noticeable in 5th gear. When the gearbox engages 5th, the revs drop from 4th gear to 5th gear. Under light throttle (i.e. not accelerating to increase speed), just after the gear change, the revs hold at one level, BUT THEN IT DROPS almost 300-500 revs.
To summarise, the box changes from 4th into 5th, and revs drop accordingly. Revs hold for 1-3 seconds at that level but then revs drop further 300-500 rpm after that.
Once this happens, the car feels very sluggish (almost like something slipping). After the revs have dropped as described, if i give the car full throttle it doesn't accelerate as it should. In fact, on some uphills the car just refuses to pick up speed and i have to pull it down into 4th first, then when it changes back into 5th it will maintain the acceleration until i ease off the throttle and then the revs drop again.
Car has 160,000kms 0r 100,000 miles. Had it since brand new. The gearbox oil did run low once around 80,000kms / 45,000 Miles. The problem started around 120,000kms or 75,000 miles.
Really have no clue what could be causing this.
Have changed the diff once already with no success.
Anybody have any ideas???
|Is there a difference when you put the sports on in the gearbox?|
|when you give more gas after the revs drop and you say it doesn't seem to have power, do the revs jump real high but you just don't seem to go?|

When i put it in sports, the car stays kicks back into 4th gear and never changes up into 5th.*
What i did notice throughout all the gears though (1-5), is when i drive in economy mode, the gearchanges are way too early.* If i pull away from a standstill, with about 70% throttle the car will accelerate ok from pull off but it will change gears around 3,500rpm (maybe less).*
